HCD High Current Disconnect Switches FRIEM Việt Nam

HCD High Current Disconnect Switches

FRIEM can supply a wide range of high current isolating/ disconnect switches. Identified case-by-case among different technologies, in order to achieve the most efficient and maintenance -friendly layout.

Protections

The isolating/disconnect switches can either use sealed contact assembly, to increase safety and withstand chemical environment, or mechanically independent mobile contact arms, provided with high-pressure springs. Electrical contacts are provided with silver to silver contact. Upon request the isolating/disconnect switches can be customized with input and output terminals in aluminium or silver-plated copper, two-poles or changeover design by side association of two disconnects, manual, pneumatic or motorized actuators. All high current disconnect switch manufacturing activities meet ISO 9001 standards.

Installation

Isolating/disconnect switches can be installed in any position and directly into the busduct system. Switches are available for connection either to Copper or to Aluminium busduct bolted or welded. Disconnects are self-supporting, however busbar supports must be designed to withstand the switch’s additional weight. All the engineering needed for the installation of the switches and their installation to the busduct is done by FRIEM. The disconnect switches can be operated at no load (No-load Disconnect switches) or on load (Load-break Disconnect switches).
