PO Non-shrinkable Tubing
IEC 60502.4 EPDM Material Submersible

Woer Separable Connectors Rated to 12/20kV (24kV) · 6/10kV (12) & 8.7/15kV (17.5)

Premium separable connectors designed for medium voltage cable systems. Manufactured from high‑quality EPDM rubber, offering excellent electrical properties, anti‑tearing, anti‑ozone, anti‑corrosion and high mechanical strength. Fully compliant with IEC60502.4 and GB12706.4.

High‑quality EPDM – anti‑tear, anti‑ozone, anti‑corrosion
Advanced injection technique – no layer surface gap, low partial discharge
Fully sealed & insulated – submersible (can be used in water)
Optimised electric field structure – even outer screen, earthing resistance <1000Ω
Ensures cable surface at zero potential – operator safety

Before installation, please check whether the cable size is matching the connector size.
