Siemens Switchgear Cable Connectors Terminations

Siemens – Gas Insulated Switchgear For Secondary Distribution MV Medium Voltage Power Systems Up To 33kV

  • by Chris Dodds T&D - estimated reading time 5 minutes

Thorne & Derrick International, based in the UK, are a leading distributor of cable accessories and connection systems for 33kV cables – this includes heat shrink/cold shrink joints, terminations and EPDM type screened separable connectors manufactured by Nexans Euromold.

The following information enables the specification and selection of the correct 33kV cable plug type termination or connector to suit medium/high voltage power cables used with Siemens NXPLUS C Wind switchgear.

Specifically, we confirm the current approved 33kV cable connectors for use with Interface C 33kV Bushings on gas insulated switchgear.

The following information table enables the selection and outlines the possible cable connection types (T-Plugs, Coupling Insert & Screened Separable Connectors) and MV surge arresters compatible with Siemens NXPLUS C Wind switchgear 33kV/36kV.

Screened cable T-plugs, also known as separable connectors, are specified to terminate and connect 33kV power cables into Siemens NXPLUS C gas insulated switchgear – the external semi-conductive layer must be earthed normally via a cable connector.

Insulated cable T-plugs (without semi-conductive layer) are not permissible – this type of MV cable plug or connector is prone to partial discharge due to the proximity to earthed parts of the switchgear. Partial discharge destroys the MV cable connector causing an arc between phase and earth.

The connection of conventional 33kV cable sealing ends or terminations via elbow adapters is not permissible either as this type of medium voltage power system is also insulated but not screened (no external semi-conductive layer).

33kV Cable Terminations – Raychem Heat Shrink Terminations (VSLP9 Switchgear)

33kV Cable Terminations

  • Application: 33kV Cable Terminations –  XLPE Cables Into VSLP9 Type Switchgear
  • Cable Jointer: Craig Kilkenny – EHV Cable Jointer / Fitter
  • Product Category: MV HV Power Cable Terminations

 

  • by Chris Dodds T&D - estimated reading time 5 minutes

33kV Cable Terminations Installation

Here, high voltage substation cables are shown connected and terminated into switchgear using 33kV cable terminations.

The copper earthing tapes are used to bond all of the cable glands together which are providing mechanical retention to the 33kV high voltage power cables.

The earth tapes are clamped and attached to the substation earthing system as they are insulated from the 33kV cable box and high voltage oil-filled switchgear. The whole bank of HV switchgear is insulated from the ground and has its own earth which runs through a Current Transformer (CT) for protection reasons – the separate ‘frame earth’ is painted green in the photograph below. The stand for the cable cleats was also bonded to the substation earth. As there is a steel sandwich plate fitted to the front of the wooden cable cleats the threaded bar used is stainless steel to avoid circulating currents.

Sealing Cable Ducts 33kV

Client specified expanding foam has been used to seal the substation cable ducts within the high voltage substation – outside the substation the 33kV cable ducts were effectively sealed using a specified system to provide certain protection against water ingress and gas migration using recognised systems such as the CSD RISE duct seal or Filoform Filoseal re-enterable cable seals.

The insulating oil is usually heated before the high voltage cable box is dismantled by venting it above and heating with halogen heaters.

Stripping & Terminating 33kV Cables

The 33kV cables were stripped using the correct cable jointing tools – the PVC cable sheath was thoroughly stripped from the high voltage power cable using the Boddingtons “plough” type sheath stripper. The cable jointer then removed the XLPE insulation cleanly and without damaging the cable using Alroc LH2 tool suitable for cable stripping HV cables up to 60mm.

Finally, Alroc CWB 18-60 tool was used to remove the bonded semicon from the cable – the “blue tool” manufactured by Alroc is preferred by jointers for working on medium/high voltage power cables where a clean square cut of the semicon without jagged finish is vital to the long term reliability of power cable performance.

Semicon Cable Stripping 33kV 11kV

Poor cable jointing skills with respect to MV-HV cable preparation can create future cable failure potential – it is critical a skilled jointer uses the correct cable tools to prepare MV-HV cables before installing joints, terminations or connectors up to 33kV.

Comments from fellow HV cable jointers:

Jimmy Nicklin: “Nice job Craig Kilkenny. I did a nine bank of these 15 years ago and is quite the breakdown and remake to do.”

Dean Wilson: “Nice neat work Craig Kilkenny and yes I agree Jimmy Nicklin it’s getting the old oil out that’s a job in itself!”

Andrew Brezovszky:  “Very neat 33kV cable terminations !”

3M Cold Shrink vs Heat Shrink

January 24th, 2018
How To Abandon Cables

A series of How-To videos for repairing, jointing and terminating cables using 3M Cold Shrink & Scotchcast products.

Cold Shrink

This video by 3M Electrical shows the benefits of using 3M Cold Shrink compared to heat shrink cable accessories to insulate, joint, repair and terminate cables.

3M cold shrink tubes utilise a unique cold applied delivery system which is designed to make cable jointing, insulating, termination and abandonment as simple as possible without any of the inherent workplace risks associated with “hot-working” and using naked flames to activate heat shrink type cable accessories.

Cold shrink reduces the risk of damaging XLPE cable insulation caused by scorching or over-heating of the cable by the jointer. No cooling time is required before energising cables.

Cold Shrink Benefits

Installation is fast and an easy one-step installation process:

  • Labour Savings – enables installation of cable accessory in 1/3 of the time or less compared to heat shrink equivalents
  • Tooling – no special heating tools or “hot-work” work permits required
  • Compact – smooth profile cold shrink limits volume displacement on cable tray where congregated cable joints are located
  • Outdoor – resistant to weathering for continued outdoor service in environmental and exposed locations
  • User Friendly – easy to learn and train with less installation steps
  • More Cold Shrink Videos | Cable Abandonment | Cable Terminations MV HV

➡ See How To Use Cold Shrink Tubes.  

3M Cold Shrink Tubes - EPDM Rubber

3M Tubes – available in EPDM Rubber or Silicone

Depending on the application cold shrink is available manufactured in EPDM Rubber or Silicone – contact us to discuss your application.

Cold Shrink creates a static and stable cable seal that does not expand or contract with the cable under thermal cycling of LV-HV cables, potentially leading to the creation of voids between the cable accessory and the cable which could lead to a joint or termination failure.

3M Cold Shrink

Cold Shrink – invented by 3M over 40 years ago and now the preferred technology for heat-free jointing, terminating, sealing and abandonment of LV HV cables

We hope you find this video informative and educational, contact T&D for technical support, quotations and stock availability for 3M Cold Shrink.

Trust Cold Shrink

  • Low Cable Failure Rates*:
    – 0.067% for Cold Shrink Cable Joints & Cable Splices

Switchgear Bushings & Cable Connectors

The following information has been provided to enable to correct selection and specification of MV Bushings and Separable Connectors used to connect and terminate medium/high voltage power cables into Schneider RM6 gas insulated switchgear and Ring Main Units (RMU) up to 24kV.

General

  • The profiles, contacts and dimensions of the Schneider RM6 connection interfaces are defined by the IEC 60137 standard
  • 100% of the epoxy resin interfaces undergo dielectric testing at power frequency and partial discharge tests
  • Insulated connectors must be used in order to guarantee the dielectric performance

Appropriateness For Use

Types of connection interface

Types of Connection Interface

The bushings carry the electrical current from the outside to the inside of the MV switchgear enclosure, which is filled with SF6 gas, ensuring insulation between the live conductors and the frame for MV power distribution.

There are 3 types of MV bushing, which are defined by their short-time withstand current:

  • Type A Interface Bushing: 200 A: 12.5 kA 1 s and 31.5 kA peak (plug-in)
  • Type B Interface Bushing: 400 A: 16 kA 1 s and 40 kA peak (plug-in)
  • Type C Interface Bushing: 630 A: 25 kA 1 s, 21 kA 3 s + 62.5 kA peak (disconnectable M16)

➡ For further information on Euromold Connectors for all other Interface Bushings up to 66kV please see the following information:

Nexans Euromold

The Euromold brand of MV Cable Connectors manufactured by Nexans for 11kV 33kV 66kV connection of medium/high voltage power cables into gas insulated electrical equipment.

How To Define The Cable Connectors Interface

The connection interfaces depend on specific criteria, such as:

Installation

  • Current rating of the connected equipment: 200, 400, 630 A
  • Short-time withstand current for 12.5 kA, 16 kA, 25 kA switch and circuit breaker functions
  • For the fuse-switch combination function, as the short-circuit current is limited by the fuse, the connection interface will be of type A (200 A)
  • Minimum phase expansion length
  • Connection type: plug in: multicontact ring, disconnectable: bolted
  • Output position: straight or elbow connectors

MV Medium Voltage Cable

  • Specified voltage: of the cable, of the network
  • Type of conductor: aluminium or copper
  • Cross section in mm2
  • Primary insulation diameter
  • Cable composition: single-core or 3-core
  • Insulation type: dry, paper impregnated (non-draining type)
  • Type of screen: copper tape or copper wire screen
  • Armour: SWA (steel wire armour), AWA (aluminium wire armour) or unarmoured (copper wire screened)

Gas Insulated Switchgear – Schneider RM6

  1. Stainless steel tank filled with SF6 gas, sealed for life and containing the medium voltage (MV) busbar and all live switching components such as the switch-disconnector, earthing switch, the fuse switch combination or the MV circuit breaker
