15kV European 630/1250A Shielded Detachable Connector

Application areas:

Used in high-voltage electrical equipment, suitable for TYPE “C” bushings conforming to EN 50180 & EN 50181 standards, providing full insulation and shielded, touch-accessible connection between the bushing and cable.

Product Description

15kV European 630/1250A shielded detachable connector, including: WEBⅢ 15/630 (1250) European new front plug, WEBKⅢ 15/630 (1250) European new rear plug, European rear-mounted surge arrester (multiple models). The product is divided into two series: 630A and 1250A.

The WEBⅢ 15/630 (1250) European-style new front-mounted plug is suitable for the (cross-linked power cable) incoming and outgoing line terminals of ring network switchgear, connecting to the incoming and outgoing line bushings of the switchgear, the wall bushings of cable branch boxes, and double-through bushings. It is also suitable for prefabricated substation equipment. It provides a fully insulated and 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 bushing socket of the switchgear; 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 WEBKⅢ 15/630 (1250) European new rear plug and WEBⅢ 15/630 (1250) European new front plug, or another WEBKⅢ 15/630 (1250) European new rear plug connection, provide extended cable connection loops (branches), which cannot be directly connected to bushings. The tail can be directly plugged with an insulating plug, or 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.

4. Miniaturized structure, adapting to the trend of box design.
