Application
These accessories suit underground networks, substations, switchgear rooms and cable routes in industrial and renewable projects. Indoor types are for clean, enclosed rooms; outdoor types carry shed profiles that cope with rain, salt fog and UV. For cable runs in heavy pollution or extreme conditions, tell us about the site - we will flag whether the standard range is enough or whether you need a special configuration.
We have shipped them into distribution and industrial projects across different markets, usually via distributors or as part of transformer and switchgear packages.
Construction/Design
The accessory is three parts doing three jobs. The outer body - EPDM or silicone rubber - provides insulation and seals against moisture. Under it, a stress-control layer evens out the electric field where the cable screen is cut back. Metal connectors tie the assembly to the conductor. Nothing exotic; the value is in doing each part correctly, which is why we control the raw materials ourselves.
Standards & Testing
We design and test to IEC 60502-4, the standard that defines the electrical and mechanical test requirements for LV/MV cable accessories. Factory tests cover dielectric withstand, partial discharge, and mechanical and sealing checks, and we send the test report with each batch. The applicable standard can vary with the model, so we confirm it against the specific unit you order.
Optional Configurations/Customization
You can choose termination type (indoor/outdoor), installation method (heat-shrink / cold-shrink), conductor range and shed profile. For colour, logo or unusual cable dimensions we run a quick technical check before quoting - easier than sorting out a mismatch later.
Packaging & Delivery
We pack for ocean freight - cartons or wooden crates, cushioned so the accessory is not knocked or scratched in transit. Each batch ships with a packing list and the factory test report. Lead time depends on quantity and model; we confirm it in the PI before you pay.
