Highland HV/MV Solid Soft Starter Cabinet
The highland HV/MV solid soft starter cabinet of Gozuk is applicable to the environment at an altitude between 2,000m and 4,000m. The highland soft starter vary quite a lot in the terms of design, manufacture, installation and use from the flatland product and insulation correction factor is specially employed for the design of the highland product to meet the highland environment conditions.
Insulation correction factor is indicated by Ka
For example, when the altitude is 3,000m,
The highland soft starter cabinet, therefore, increases the insulation level between phases, phase and earth wire and isolating distance to meet the requirements of high altitude environment and requires that the net air clearance should not be less than 160mm.
The configuration of the highland HV/MV solid soft starter cabinet is the same to Gozuk standard soft starter while the cabinet dimensions can be customized according to the actual conditions.
Insulation correction factor is indicated by Ka
Ka=1 / (1.1 - h*10-4)In which, h indicates the altitude of the installation site.
For example, when the altitude is 3,000m,
Ka=1 / (1.1 - 3000*10-4) = 1 / (1.1 - 0.3) = 1 / 0.8=1.25The withstand voltage of vacuum contactor is10kV when the altitude is below 1,000m, while it should be raised to 10×1.25=12.5KV when the environment altitude is 3,000m.
The highland soft starter cabinet, therefore, increases the insulation level between phases, phase and earth wire and isolating distance to meet the requirements of high altitude environment and requires that the net air clearance should not be less than 160mm.
The configuration of the highland HV/MV solid soft starter cabinet is the same to Gozuk standard soft starter while the cabinet dimensions can be customized according to the actual conditions.
