Insulating Articles Match High Voltage Switchgear, Insulator for GIS, PASS H.GIS Insulators

PRODUCT INTRODUCTION

Insulating Articles Match High Voltage Switchgears

PRODUCT DETAILS

The single-phase or 3-phase insulators, insulating tubes and insulating rods are match 35~1000kV GIS PASS

or CB high voltage switchgears. Their dimensions, technical parameters and service environments can be

designed according to the requirements of the clients.There are many variants for each kind of the insulator, there are with metal flange or without metal flange,open or close in the epoxy resin, open or close in the insert and so on.

High Voltage Switchgear Performance requirements

1)Rated voltage: 35kV, 66kV, 110kV, 132kV, 150kV, 220kV, 330kV, 380kV, 500kV, 750kV and 1000kV and so on.

2)Power-frequency withstand voltage performs the standards of GB/T 4109-2008 or IEC 60137:2003.

3)Rated lightning impulse, switching impulse and chopped lightning impulse withstand voltage perform the standards of GB/T 4109-2008 or IEC 60137:2003.

3)Measurement of partial discharge performs the standards of GB/T 4109-2008 or IEC 60137:2003.

4)Mechanical strength: performs the standards of GB/T 4109-2008 or IEC 60137:2003. Or according to the requirements of the clients.

5)Sealed performance: The products must support the rated pressure of SF6, and their gas leak are not exceed 0.1% annually.

Note: These are the routine performance requirements in the above listed, if there is any different required, we can design according to the requirements of the clients.
