Cable Winch | Customised & Refurbished 5 Tonne Cable Pulling Winch

Cable Winch

• uploaded by Chris Dodds - Sales & Marketing Manager with Thorne & Derrick International

Thorne & Derrick, the Specialist Distributor of LV HV Jointing, Earthing, Substation & Electrical Eqpt have supplied a cable winch requirement to a leading provider of offshore power distribution to the renewable and oil/gas sectors. 

The refurbished and customised 5 tonne cable winch was customised to enable the pull and installation of medium/high voltage power cables – the winch was delivered within 2 weeks from receipt of client order. The cable winch enabled the installation of cable runs up to 120 metres from the variable frequency drive (VFD) to the compressor junction box which goes from underground cable trench to above ground and onto the cable containment ladder racking system.

The cable winch modification was based on the standard SEB TW5000 version with additional cable tension dynamometer – the dynamometer continuously checks the cable pulling tension to ensure the forces do not exceed the recommended guidelines.

Additional features Pre-Set Load Function, Load Display, Test Certification & Load Cell.

Bevelling The Edge Of The Core Insulation During Installation Of Nexans Euromold Connectors – Part 3

Euromold Connectors

Bevelling The Edge Of The Core Insulation During Installation

In this Webisode Nexans discuss bevelling or chamfering the edge of the core insulation during installation of the Euromold connectors.

Carefully read the installation instructions that come with the separable connector kit in order to perform the correct preparation for the specific cable you have at hand. For most cable types, the first steps are the removal of the cable outer sheath and removal of the semi-conductor screen.

Then remove the core insulation from the conductor. Standard core insulation removal tools will leave a sharp, 90° edge of the insulation. If not taken care of, this might damage the inside of the cable accessory during installation.

A sharp edge will also scrape off silicone grease, making it more difficult to install the cable adaptor for the Euromold connector.

So to avoid cable damage and to assure an easy slip-on of the cable accessory, the edge of the core insulation should be bevelled using an appropriate tool. Tools that provide a 45º chamfer are often used in the field, but tools that provide a smooth radius are even better.

For some conductor sizes, an installation tool is available to further ease the installation of the cable adaptor.

Different Insulating Epoxy Plugs & How To Install The Cap On Nexans Euromold Interface C Compact Connectors – Part 2

Nexans Euromold Interface C Compact Connectors

Different Insulating Epoxy Plugs & How To Install The Cap

In this Webisode Nexans will discuss the different Epoxy Plugs and how to install the cap on the Euromold Interface C Compact Connectors.

When your maximum medium voltage system is 24kV, you can see the Euromold BIPR insulating epoxy plug without locking point during the installation of the separable connector.

When the maximum medium voltage system is higher than 24kV, such as 33/36kV, you have to use the Euromold BIPA insulating plug. This epoxy plug has a metallic voltage detection point with a locking point on the top that must be connected to the cap.

1. Start the installation of the cap with cleaning the inside of the cap and the outside of the Euromold connector and insulating plug
2. Place the nylon vent rod along the insulating plug to exhaust air during cap assembly
3. Then push the cap firmly over the connector and onto the insulating plug until it cannot advance any further. Only when use the BIPA insulating plug you have to press the centre of the cap onto the locking point until it snaps into place
4. Press the cap on all sides to make sure it is well positioned over the connector. The pulling tab of the cap needs to be positioned downwards. Remove the nylon vent rod
5. Re-press the centre of the cap onto the locking point to ensure it is still in place

Failure by the Jointer to observe the above procedure can lead to premature Partial Discharge development and consequently product failure of the Connector terminated onto the MV HV switchgear or transformer bushing interface.

Water Sealing, IP Rating & Temperature Range Of Nexans Euromold Connectors – Part 1

Euromold Connectors

Water Sealing, IP Rating & Temperature Range

In this Webisode Nexans answer frequently asked questions regarding water sealing, IP rating and temperature range of the Euromold connectors.

Are Euromold Connectors Watertight?

Yes, these EPDM connectors are completely watertight for the connection and cable termination of medium/high voltage power cables to electrical equipment including ring-main units, switchgear and transformers.

No ingress is possible at the bushing interface, rear interface or cable entrance of the Euromold connector.

Furthermore, the cable adaptor provides water sealing of the cable itself.

In the case of copper wire screen, water sealing mastic is applied on the cable jacket or sheath.

Therefore the IP rating of the Euromold connectors is IP67. This means that the screened separable connectors are completely dust tight and suitable for immersion in water of 1 metre depth or less.

The operating temperature range of these Euromold connectors is minus 60 degrees to 130 degrees Celsius.

However, due to the temperature range of an Epoxy Bushing the actual temperature range of the application is from minus 40 degrees to 115 degrees Celsius.
