European Style Front Connector

Detailed Description

The European Style Front Connector – available in models EX-QJ-35/630A and EX-HJ-35/630A – is a Switchgear Insulation Component rated for 35kV and 630A. It employs a 630A pre‑molded connector to link single‑phase or three‑phase insulated cables to various equipment, including transformers, switchgear, and distribution branch boxes. This connector fully complies with the Type‑C bushing interface as specified in European standards EN50180 and EN50181.

Technical Specifications

The Technical Specifications of this European Style Front Connector define its physical interface and conductor compatibility for high-voltage cable termination applications at 35kV class. The rated voltage of 35kV and continuous current of 630A establish the operating limits for both models, EX-QJ-35/630A and EX-HJ-35/630A, ensuring reliable performance under normal load conditions in transmission and distribution networks. The Φd dimension specified in the Technical Specifications—ranging from Φ24.5 to Φ47—determines the compatible conductor cross-section, covering sizes from 25mm² up to 630mm² across ten standard configurations. This European Style Front Connector is designed as a pre-molded 630A interface that facilitates direct connection between insulated cables and switchgear apparatus. As a certified Switchgear Insulation Component, the EX-QJ-35/630A and EX-HJ-35/630A models of this European Style Front Connector fully comply with the Type-C bushing interface per European standards EN50180 and EN50181. Each Technical Specification parameter—voltage, current, Φd dimension, and dual cross-section ranges—has been validated to ensure that every Switchgear Insulation Component meets the stated performance criteria. Proper selection of the correct Φd size from the Technical Specifications table ensures optimal electrical contact and mechanical fit for this European Style Front Connector in 35kV distribution networks.
