33kv 35kv 110kv 115kv 132kv 138kv 220kv 230kv Dead Tank Current Transformer Outdoor Electric Substation Equipment
It is oil paper insulation structure. The main insulation is wound from high voltage cable paper, and is placed several capacitor screen of voltage division in the primary insulation, which can improve electric field distributing and decrease the consumption of insulation material. It will be immersed with transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance of insulation, rich successful experience, a long life time.
?Perfect fluidity performance of transformer oil is good for heat dissipation, it also has self recover ability for the failure of partial discharge caused by air bubble and dust.
?The current ratio can be changed easily by switching the connection method of Primary winding to series or parallel.
?Hermetically sealed stainless steel metallic bellows is installed on the top, which protect the transformer oil from moisture and extend the life time, also there is a oil level gauge on the bellows for observing the changing of oil volume.
?Two optimization design external insulation types offered for user for inside and outside electric field without discharge
1. Composite insulator
2. High strength porcelain bushing
?There is a multi function oil drain valve on the base, which make it more convenient for sampling, draining.
?All adopted insulation parts are environmental protection material.
?Secondary terminal board is made of epoxy casting, the seal performance is more reliable.
?The base uses spray painting or hot galvanizing, which gives a high degree of corrosion resistance.
?Fasteners and nameplate are stainless steel.
