Among 70% of the parts and components, local companies account for more than 70% of the market share, and some of them are almost exclusively owned by local suppliers, such as body parts, gearbox parts, GPS, brake pads and other products. However, in the field of top ten high-tech auto parts such as EMS engine control system, ABS system, three-way catalytic converter, automatic transmission, high-pressure fuel pump, foreign-funded enterprises have absolute competitive advantage and control over 70% of the market share. Almost all products are monopolized by foreign capital.

product description

GFDD series of top-blow dry-type transformers with cross-flow cooling fan (hereinafter referred to as: dry-type cross-flow cooling fan) is mainly used for dry-type transformers cooling capacity, and electronic equipment, power distribution cabinets, high and low voltage switchgear forced air cooling . Dry-type transformers coupled with the fan cooling, 40 ~ 50% capacity increase can be run, thereby greatly increasing the carrying capacity of dry-type transformers and prolong the service life of dry-type transformers, is widely used by domestic and foreign manufacturers the most cost-effective the way.

The product strictly according to JB / T8971-1999 "dry-type transformers with cross-flow cooling fan" design and production of motor set, the rotor core using high-quality cold-rolled silicon steel; low noise bearings; impeller using aluminum alloy surface electrophoresis, and then through the fine Dynamic balance adjustment; left and right end plate made of stainless steel stamping, into the wind board, the wind board and the wind deflector aluminum alloy buckle combination; the entire fan structure is reasonable, handsome in appearance, with air volume, noise, temperature rise Low, long life, stable operation, easy installation and so on.

working principle:

The series of cooling fan for dry-type transformers, fans placed on both sides of the lower part of the transformer coil, the wind blowing directly into the transformer coil high and low pressure cooling air duct, cooling effect is obvious, can protect the normal operation of the transformer and extend its service life (Fan open, stop and over-temperature alarm transformer, over-temperature trip and other functions have temperature control device to provide).
