Separable Connectors Mated with 
EN50180&50181

Woer produces a range of separable Elbow, Straight and Tee connector kits. 
Our separable connectors are widely used in switchgears, transformers, cabinets 
and other electrical equipments. It is made of EPDM or silicone rubber with 
integrated field control. Woer adopts advanced triple-layer (a conductive inner 
layer, an insulation layer and a conductive outer layer) injection technique to 
guarantee the interface property to avoid gaps between layers and decrease partial 
discharge maximally. Our separable connectors are mainly delivered in 3-phase kit. Each 
kit contains all the necessary accessories. 

Woer products have been designed and tested per  IEC and other industry standard 
including:

Separable Connectors Mated with 
IEEE 386

Woer produces a range of separable Elbow and Tee connector kits. Our separable 
connectors are widely used in switchgears, transformers, cabinets and other electrical 
equipments. It is made of EPDM or silicone rubber with integrated field control. Woer 
adopts advanced triple-layer (a conductive inner layer, an insulation layer and a 
conductive outer layer) injection technique to guarantee the interface property to 
avoid gaps between layers and decrease partial discharge maximally. Our separable 
connectors are mainly delivered in 3-phase kit. Each kit contains all the necessary accessories.

Woer products have been designed and tested per IEEE and other industry standard 
including:

interface conforms to type C according to EN50180, EN 

50181 and DIN 47636.

Indicate the circuit status with flicker warning the fault
