600A Reducing Tap Plug

​

 I. Product Overview

600A Reducing Tap Plug is a high-voltage lead-out component used for high-voltage distribution equipment (such as ring main units, box transformers). It adopts a fully insulated and fully sealed design. It is usually made of epoxy resin or silicone rubber materials. It possesses excellent electrical performance and mechanical strength, and is a key component for connecting the internal and external cables of the equipment.

II. Main Application Scenarios

Ring Main Unit (RMU)

Function: As the inlet and outlet interface of the ring main unit, it connects external cables.

Features: Usually used in conjunction with T-type cable connectors or elbow-type lightning arresters to achieve full insulation and touchable connection, suitable for urban distribution networks and industrial parks.

Box-type transformer station (American/European style box transformer)

Function: Installed on the side wall of the high-voltage room of the box transformer, serving as the outgoing line of the high-voltage side of the transformer.

Features: Small in size, compact in installation, can effectively save the internal space of the box transformer, suitable for residential areas, commercial centers and other places.

Cable Distribution Box

Function: Used for connecting the main cable and the branch cable within the distribution box.

Features: Provides a standard 600A interface, facilitating expansion and maintenance, and supports live plug-in operation (requires special tools).

III. Installation and Maintenance Tips

Installation Direction: The flange should face upwards when installed vertically. It should face outward when installed horizontally. Ensure that the sealing ring is tightly pressed.

Sealing Treatment: The installation hole diameter should be more than 5mm larger than the embedded part of the bushing, and ensure that the sealing rubber ring is intact to prevent moisture or SF6 gas leakage.

Grounding Requirements: The metal flange and shielding layer of the bushing must be reliably grounded. The grounding resistance should comply with the specification requirements.

Anti-Fouling: In areas with heavy pollution, choose anti-fouling bushings with a larger creepage distance, or regularly clean the surface of the bushing of pollution.
