15kV 24kV 35kV 630A European Rear Joint

Our 15kV 24kV 35kV 630A European Rear Joint (also known as a European-style cable rear connector or European-style rear bushing) is a fully insulated, fully shielded plug-in cable connection device used in medium-voltage (10-35kV) power distribution systems.

It is primarily applied in ring main units (RMUs), compact substations, and cable distribution cabinets for cable entry and exit connections. Compliant with IEC and GB standards, it features high reliability, a compact design, and long service life.

Below drawing is 15kV connector for reference:

 

 

● Optimized Shielding Design:

Inner/outer shielding with surface resistance <5000Ω

Conductive shielding layer of sufficient thickness ensures operator safety during contact

Provides full insulation, complete shielding, hermetic sealing, touch-safe operation, and superior electrical performance

● Rigorous Quality Assurance:

Each separable connector undergoes AC withstand voltage testing prior to factory shipment

● Cable Characteristics:
○ Polymer insulation (XLPE, EPR)
○ Copper/aluminum conductors
○ Equipped with semi-conductive or metallic shielding

 

 

● Ring Main Units (RMUs): Cable entry/exit connections.

● Compact Substations (European/American style): High-voltage side cable termination.

● Cable Distribution Cabinets: Multi-circuit cable branching.

● PV/Wind Power Projects: Medium-voltage collector line connections.
