Disconnectors DSH Type 24kV/630A

Medium Voltage Disconnectors (20-24kV), single pole operating at 630 A and three pole at 630 A Nominal Current. Capable for outdoor installation, manually operated with vertical break.

The Disconnectors are built with porcelain or composite insulators and are usually used in 20/24 kV overhead distribution lines.

They are manufactured by STALCO S.A. according to IEC 62270-102 ,IEC 60694 (IEC 62271-1) Standards and the Technical Descriptions of the HEDNO:

This type of disconnector has been manufactured by our company for more than 30 years. Our products have been operating successfully in the Greek power grid throughout all this time.

Description

Manufactured to withstand the harshest environmental conditions and high pollution levels. The base of the disconnector and all non-current carrying parts are made by formed hot dip galvanized steel.

The insulators are made of high-quality brown porcelain. The disconnector's contacts, terminals and blade are made of tin-plated copper.

The contacts are self-cleaning and always maintain constant pressure and once secured in the closed position can withstand seismic, wind and other vibrational forces without opening.

All screws, nuts and washers are made of hot dip galvanized steel to ensure long and trouble-free operation.

The operation of the Single Pole Disconnectors is done manually using a hookstick, whereas the Three Pole Disconnectors with a metal handle. The Disconnectors can be mounted vertically or with a 30o angle from the vertical on a steel structure.
