MV Joints & Cable Preparation

1. MV Cable Preparation. The medium voltage cables are expertly prepared by the cable jointer/splicer using basic tools such as cable jointing knife, needle nose pliers and a scale ruler – no specialist cable jointing tools were used to complete this MV cable preparation or joint. To achieve this level of precision and accuracy without damaging the cable and jeopardising the medium voltage cable joint requires an exceptional skill level. The 15kV cable manufactured by Okonite is 750 KCMIL with EPR insulation and ready to be connected using Prysmian cable joints. The white tape overlap section between the copper tape screen and semicon screen is used to secure the medium voltage cable shielding in place.

2. Medium Voltage Cable Joints – Fire Proof. The medium voltage cable joint is over-wrapped to provide fire protection and arc proofing. This MV cable joint was for a new medium voltage circuit with several cable chambers so the 15kV cable is actually open on both ends and not grounded – “the phasing is not completed until every medium voltage cable joint or splice is completed except the first and last, and that’s when we phase it,” comments Christopher.

3. Medium Voltage Straight Joints – no tee (or branch) cable joints were installed, “this particular MV circuit isn’t very long and goes from substation to a dozen or so manholes, then the medium voltage cable terminates at a riser. If our circuit has wyes or tees, we still typically phase at the end,” added Christopher. Branch joints can be used to split main feeder cables into two cables that can be directed to other loads. 

Cable Pulling – the cable gang pulling 15kV 500MCM medium voltage EPR cable. Here the contractor is preparing to piece out a circuit that runs through the middle of the manhole (cable splicing or jointing chamber).

Prysmian Elaspeed Cable Joints

Prysmian Elaspeed cold shrink cable joints and splices are medium voltage cable accessories extensively specified in North American markets – Elaspeed are not molded cable joints. Elaspeed cable joints feature a core constructed from ethylene propylene rubber (EPR) on a vertical triple extruder which maintains concentricity on medium voltage cables. Cable joints are installed cold-applied without the requirement for heat or open flames associated with heat shrink cable joints.

Watertight Cable Joints

The circumferential pressure of the Prysmian Elaspeed cable jacket in conjunction with the cold flow properties of the mastic supplied with the cable joint kit will prevent water ingress. The Elaspeed MV cable joint has successfully passed external water pressure tests of 45 psi. In addition, the tight interface between the cable and cable joint body can withstand pressures up to 30 psi.

Compact Joints

Prysmian Elaspeed joints mimic the behaviour and performance of MV EPR cables in terms of bending radius in tight manhole situations – cable joints or splices can be bent to the same radius as the cable without impacting upon the performance of the joint. The small and smooth profile of the completed joint occupies less installation space where confined space working does not permit oversized joints.

Medium Voltages

Prysmian Elaspeed joints are available in the following voltage categories: 15kV, 25kV, 28kV, 35kV – the cable joints are available to also connect 3 core conductor armoured cables and aluminium inter-locked armoured MV-105 cables, including TECK Cable. Transition joints are also available to splice 3 or single core conductor paper lead (PILC) cables to 3 or single core conductor EPR / polymeric cables.

ATEX Cable Joints – Jointing Cables In Hazardous Areas Zone 1 & Zone 2

Cable Joints & ATEX

Uploaded By: Chris Dodds - reading time 5 minutes

The ATEX Directive covers an extensive and diverse range of equipment potentially including electrical equipment and cable accessories used on fixed offshore oil and gas platforms, in petrochemical plants, mines, flourmills and other areas where a potentially explosive atmosphere may be present – these are commonly referred to as “hazardous areas” and categorised according to the potential explosion risk into Zones under the European Directive known as ATEX. 

In this post we clarify the situation with respect to the relationship between the product category “LV Cable Joints” and the European hazardous area ATEX Directive.

ATEX

A potentially explosive atmosphere exists when a mixture of air and flammable gases, vapours, mists, or dusts combine in a way that can ignite under certain operating conditions – this is referred to as a hazardous area and depending on the concentration levels this is categorised into Zones according to degree of risk as referenced below.

The ATEX Directive 2014/34/EU covers equipment and protective systems intended for use in potentially explosive atmospheres.

The Directive defines the essential health and saftey requirements and conformity assessment procedures, to be applied before products are placed on the EU market. It is aligned with the New Legislative Framework policy, and it is applicable from 20 April 2016, replacing the previous Directive 94/9/EC.

A Guidance document on the ATEX Directive transition from 94/9/EC to 2014/34/EU (371KB) is available as a download below, with a list of frequently asked questions and answers.

In very broad terms, there are 3 pre-conditions for the ATEX Directive to apply to the
electrical equipment and cable accessories for use in potentially explosive atmospheres and hazardous areas:

a) must have its own source of ignition;
b) be intended for use in a potentially explosive atmosphere (air mixtures); and
c) be under normal atmospheric conditions.

When used as directed, 3M cable joints and cable accessories do not have a source of ignition. The firing of an explosive atmosphere may be caused by a short circuit, but when installed according to 3M instructions, their cable joints (both resin and Cold Shrink) are safe against short circuits. To conclude, 3M cable joints and Cold Shrink accessories are not within the scope of the ATEX Directive.

T&D Approved Abtech Distributors | Hazardous Area Enclosures

Hazardous Area Zones

• Zone 1 – according to ATEX a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.
• Zone 2 – according to ATEX a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, persists for a short period only.

Cable Joints

Why Specify & Install 3M Cable Joints?

Although cable joints are not formally certified according to ATEX there are several minimum specification and performance requirements for cable joints when being used to connect, repair or joint cables in hazardous areas.

Standard industrial cable joints will not provide adequate electrical insulation and mechanical protection – they utilise polyurethane resins which are not hydrocarbon resistant and will suffer chemical and molecular breakdown overtime when exposed to aggressive and corrosive atmospheres. Eventual failure of the cable joint will cause power outage and the need to cut-out the failed cable joint and re-joint using a suitable product.

3M LVI-3 type cable joints include specially formulated 3M Scotchcast 1402FR resin – this resin is hydro carbon resistant, flame retardant, halogen free and chemical resistant for use in hazardous area locations.

For this reason, 3M Scotchcast is the industry standard for hazardous area cable jointing and offshore cable joints where ATEX Directive stipulates Zone 1 or Zone 2 certified equipment must be installed – this range of cable joints suitable for power, control and instrumentation cables are approved and in service at LukOil, Royal Dutch Shell, Total, Chevron, Exxon Mobil and many other international onshore and offshore oil and gas exploration companies.

Article 500 of the National Electrical Code (NEC)

What Is NEC?

The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring, cables and equipment in the United States forming part of the National Fire Codes series published by the National Fire Protection Association (NFPA), a private trade association.

According to NEC, Hazardous (Classified) Locations (HL) are defined as areas where fire or explosion hazards may exist due to the presence of flammable gases, vapors, dusts or fibers/flyings. The 2014 National Electrical Code (NEC) – NFPA 70 categorises these locations by Classes, Divisions and Zones and imposes strict requirements for wiring methods in these locations.

Conclusion

Should you require specification or technical support to enable the selection for purchase of the correct 3M Cable Joint to joint low/medium/high voltage cables (LV-MV-HV) in hazardous areas please do not hesitate to contact us, this includes 11kV/33kV joints and terminations.
