20KV dry-type power transformer
sc(B) 20KV epoxy cast non-exciting voltage regulating dry-type transformer is a dry-type transformer by pouring enhanced high and low-voltage coils of which the internal and external surfaces are placed on the glass fiber forming net on the film with Level F epoxy resin mixture with filler through vacuum film degassing under the vacuum and pressure, and having high mechanical strength, electrical strength and heat resistant strength. 20Kv voltage grade is between 10-35KV, and it has long power supply radius, small pressure drop, low line loss, small nonferrous metal consumption and other advantages, which makes up the deficiency of 10KV distribution circuit, therefore, 20kV distribution transformer is power transformation and distribution product highly recommended by the state grid and the province.
Product characteristics
1. It is flame-retardant, explosionproof, pollution-free and maintenance-free, and can be dispersedlyarranged in the load center, thereby reducing the investment cost, and saving the expense.
2. It has low loss and good power saving effect, thereby bringing the economical and practical operation.
3. Its local discharge quantity is less than 10PC; and the coil has moisture resistance, dust resistance, high mechanical strength, and good reliability. Therefore, the expense is saved.
4. It withstands short circuit, and has good lightning impulse resistance.
5. The housing is made of stainless steel, cold plate and aluminium alloy, the type is divided into draft type and heat dissipation type, and the incoming and outgoing lines can enter from top and go out from the top, enter from the bottom and go out from the top, and enter from the bottom and go out from the bottom.
6. The transformer can be provided with the temperature control system and temperature display systemaccording to the user needs, and can be used with the temperature control system cooperatively.
