Product Features

1.Key component-iron core
The company has its own silicon steel sheet cutting line, and the iron core adopts laser-marked high-permeability silicon steel sheet.The non-punched iron core design is combined with the international marching type strapping structure to make the electric field distribution in the iron core joints well-distributed---the no-load loss can be reduced by 4-6% by comparing with similar products in the market.Special processes ensure iron core can be fixed tightly- NO shift in transportation.

2.Key component-coil

  •  Different structures (drum, foil, spiral, continuous) to meet the diverse needs of customers.
  • The end angle ring effectively improves the coil characteristics under impulse voltage-----voltage well-distributed.
  • There is an oil guide structure inside the coil to greatly reduce the temperature rise-----eliminate the risk of transformer short circuit.
  • Separate voltage regulating coil in the larger-capacity products to ensure the ampere-turn distribution in the core is well divided.

3.Key component-oil tank

  • The oil tank adopts barrel type or bell type - more stable structure.
  • The heat dissipation element adopts chip radiator-----better heat dissipation.
  • The wall of the tank is made directly by bending machine - strengthen tank’s mechanical strength and effectively improve products appearance;
  • The edge of tank is sealed with oil-resistant rubber material, and there is sealing strip mark in the tank ----- prevent leakage.
  • Strict inspection of fluorescent leak test and pressure test—prevent leakage.
