Operating Poles

An extensive range of Operating Poles manufactured from lightweight resin-impregnated fibreglass provide highest levels of electrical safety and insulation across standard voltages: 11kV, 33kV 66kV. The operating poles can be inter-connected to achieve extended lengths for both Medium Voltage & High Voltage (MV-HV) overhead line and substation applications. The poles are compliant to ENA Technical Specification TS 41-21 which combines substation and overhead line portable earthing requirements (previously covered by ENA TS 43-81).
