Product Description

 

High Voltage Inside Cone Plug-in GIS / Transformer Termination for up to 72.5kV

 

Overview

• The dry type plug-in termination is consisted of epoxy resin bushing and silicone rubber stress cone two main separately parts; insulation stop-end, test cable bushing and transition tools are also provided with main parts. They are suitable for SF6-gas-insulated switchgear and transformer.
• The inside cone socket can be installed and tested at the equipment manufacturer to ensure the quality of installation and simplify field installation.
• The inside cone socket can also be installed on site as required.
• Inside cone socket for 72.5kV is designed specially .

Key Features

Insulator: Plug-in / Pluggable
Connection voltage class(kV): ≤72.5kV
Cross section range: 185-1200sq.mm
Conductor: Copper / Aluminum
Cable structure: Wire screen /  Al-corrugated sheath / Lead sheath

Advantages

• Integral compact structure and smaller size saved space of equipment compared with conventional sytems.
• Installation and commissioning can be finished in factory especially for transformer.
• Pluggable, easy to separate cable wire from GIS equipment or transformer, all of equipment can independently carry out tests, trace cable faults, etc.
• Installation procedure is simple and fast. A working group of 2-3 people can complete the installation of 3 phases in one working day (8 hours).
• Bushing is installed in GIS cable cabinet or transformer inlet and outlet end, only plug-in termination need to be removed when changing cable, avoid gas filling and evacuating.
• All electrical connections of the inside cone termination system, insulation components are placed in the metal shell, and have a reliable seal to get full shielding, insulation and maintenance-free.
• The termination is suitable for both indoor and outdoor use, almost free from environmental conditions, pollution grade and altitude, because the terminal is not in contact with the atmospheric environment.
