Message: | 110kV 115kV 132kV 138kV SF6 Voltage Transformer is outdoor, single phase
The product adopts case-type structure. The equipment body is placed inside the case. Its central part adopts silicone rubber composite insulator or high strength porcelain insulator. Top is equipped with primary Terminals
◆It has a pressure-relief device with pressure blasting (release pressure) of 0.8MPa at side panel, free oil, no risk of explosion and free maintenance.
◆The layer insulation consists of high strength composite insulation of diamond polyester film and gas SF6, no aging and has a function of insulation restoring.
◆Density meter is mounted on the base which can show the transformer internal gas pressure (display value automatically converted to internal gas pressure at 20 ℃) and density, when transformer internal pressure drops down to alarm level, gas should be replenished.
◆Optimized designs for external insulation make inner and external electric field distribute evenly without discharge. Two type insulators are offered for user.
1. Composite insulator
2. High strength porcelain insulator
◆Sealing ring adopts special material for SF6 gas which is applicable to a area with large temperature difference and harsh environment , annual leakage rate is less than 0.5%. url:http://www.hyee-current-transformer.com |
