Product Description
MV Outdoor Off-Load Isolator Switch
(Alternating current disconnector)
TECHNICAL SPECIFICATION
Scope
Type IST off-load switchs are suitable for use in tropical zone, with a maximum ambient temperature of approximately 40 degrees Centigrade and an average temperature of approximately 28 degrees Centigrade with high humidity and heavy rainfall. The preferred operational altitude is up to 1800 m above sea level.
Electrical System
Type IST off-load isolator switch are designed for continuous operation on a 3-phase 3-wire 11, 15,22,24,27and 33,36kV,50/60Hz distribution system with the star-point of the source-point transformer earthed through an Arc Suppression Coil or Earthing Resistor.
Standards
Type IST off-load isolator switch are complied with relevant requirements of the following standards together with all current amendments;
IEC62271-102:2003 :High-voltage alternating-current disconnectors and earthing switches
IEC60129:1984 :Alternating current disconnectors and earth switches
