20kV Cold Shrink Cable Accessories (12/20kV)

Pre-expanded cold shrink terminations and joints for 12/20kV MV networks, built around IEC dimensions for European and Middle East projects.

20kV cold shrink accessories are specified for 12/20kV systems -- the IEC voltage designation used across European utilities, Gulf-grid projects and most international EPC work. The parts follow the same pre-expanded, core-pull principle as the 15kV line, but are dimensioned and tested for the higher rated stress of a 20kV class network.

The buying decision here is usually made against a cable schedule and an IEC type-test requirement rather than a single catalogue number. RMU and switchgear OEMs, solar EPC contractors and utility distributors tend to qualify one body family across a conductor range and then manage stock by cable OD. We support that with an XLPE termination selector and consistent kit contents so a missing component never stops a joint on site.

• Middle East EPC medium-voltage cable sealing
• Marine and offshore platform MV cable joints

Why cold shrink at 20kV (IEC networks)

On IEC 12/20kV systems the stress-control cone has to be right or partial discharge starts early in the joint life. A cold-shrink body carries that cone as a moulded feature, which removes the field-assembled step that heat-shrink and tape methods depend on. For EPC and OEM buyers the attraction is repeatability: the same body seats the same way regardless of which crew installs it, and there is no flame in a switchroom or cable basement.

Stress cone and kit completeness review

The stress cone is fixed in the body, but the joint still needs correct cable preparation: screen cutoff length, semi-con finish and a clean weather seal. We size bodies by cable OD across the conductor range you carry, and pack each kit with the same component set so a termination and a straight joint on the same cable do not need two different orders.

Inspection and traceability

The control plan for 20kV Cold Shrink Cable Accessories (12/20kV) is agreed with you. Batch traceability links the raw rubber lot through to the finished part and its test record.

• First-article inspection (FAI) against your cable schedule
• In-process dimensional checks at every station
• Batch certificate of conformance (COA) on request
• Lot traceability to incoming material certificate
• AC withstand and partial-discharge testing available on request
