24kV European 630A shielded detachable connector

Application areas:

For electrical equipment of 24kV and below, TYPE “C” bushings conforming to EN 50180 & EN 50181 standards provide full insulation between the bushing and the cable, with shielded, touch-accessible connection.

Product Description

The 24kV European 630A shielded detachable connector utilizes patented technology (patent number: ZL201020709860), offering simple and reliable installation. The product has been tested at DNV.GL and KEMA laboratories in the Netherlands, passing all HD629.1 and IEC60505.4 testing standards and obtaining four gold standard certificates.

24kV European 630A shielded detachable connector, including: WEB24/630 European new front plug, WEBK24/630 European new rear plug, European rear-mounted surge arrester (multiple models).

The WEB24/630 European-style new front-mounted plug is suitable for the incoming and outgoing terminals of (cross-linked power cables) in ring network switchgear, connecting to the incoming and outgoing bushings of the switchgear, the wall bushings of cable branch boxes, and double-through bushings. It is also suitable for prefabricated substation installations. It provides a fully insulated, fully sealed connection between the power cable and the switchgear or cable branch box. When in operation, the front-mounted plug is bolted to the switchgear bushing socket; its tail can be directly plugged with an insulating plug, or it can be extended to connect to a rear-mounted cable plug or a rear-mounted surge arrester. The product conforms to the C-type bushing design in standards EN 50180 & 50181.

The WEBK24/630 European-style new rear plug and WEBK24/630 European-style new front plug, or another WEBK24/630 European-style new rear plug, provide extended cable connection loops (branches). It cannot be directly connected to the bushing. The tail can be directly plugged with an insulating plug, or it can be extended to connect to another rear-plug cable head or a rear-plug surge arrester.

Features

1. Made of high-quality EPDM rubber, it not only has excellent electrical properties, but also is tear-resistant, ozone-resistant, oxidation-resistant, corrosion-resistant, and has high mechanical strength.

2. The internationally advanced three-layer injection process effectively ensures interface performance, avoids interlayer gaps, and minimizes partial discharge.

3. The inner and outer shield design of the shielded plug optimizes the electric field structure; the uniform outer shielding layer and grounding resistance of less than 5000Ω effectively keep the outer surface of the cable head at zero potential, ensuring the safety of maintenance personnel.
