PT plugs and their connecting accessories

Application areas:

PT plugs and their connecting accessories are used to provide an insulated electrical connection between 24kV and below fully enclosed elbow-type indoor voltage transformers with fuses and switchgear. The voltage transformer outgoing interface conforms to the bushing dimensions of IEEE 386 Figure 7-200 A loadbreak interface.

Product Description

European 250A detachable connector, including:

1. WEZT 15/250 European 250A elbow plug; WEZT 24/250 European 250A elbow plug;

2. WEZC 15/250 European 250A straight plug; WEZC 24/250 European 250A straight plug;

3. The European 250A detachable connector is suitable for the incoming and outgoing line terminals of (cross-linked power cables) in ring network switchgear, connecting to the type A bushings of the switchgear's incoming and outgoing lines. It provides a fully insulated, fully sealed connection for power cables to switchgear or cable branch boxes.

4. The European 250A elbow plug is used for conduit and cable with a 90-degree bend at the exit point; the European 250A straight plug is used for conduit and cable with a straight exit point.

PT plugs and their connecting accessories include:

1. WPT 15/200 15kV PT plug;

2. WAPT 25/200 25kV PT plug;

The PT plug and other cable accessories are connected via a custom PT connection assembly; the connecting cable is available in rigid XLPE cable and flexible ERF cable.
