Product Description

General:

H grade OVDT series SG (B) 10 open wide the ventilation type dry type transformer of our corporation research and development chooses H and Cs' such as Nomes, Cequin and Tufauin etc. which produced by DUPONT and QUIN-T corporation who tests the attestation by American ULinsurance, 180ºC - 220ºC insulation system  who passes optimization design possesses extinguishes and hinders to burn and hard burns even to the extent burn and the merit of safe capacity.

At the same time, having used at present advanced VIP's vacuum impregnation technology, spool whole soaks with ET-90 H grade modified heat-resisting not saturation polyester resin hinder to burn, so the paint membrance is even, bright, strong adhesive force, not crack, small part discharge and high whole mechanical strength and insulation ability, it is suitable in the environment of moist, salt and fog etc. Heavily degree pollutes, endure waiting capability is excellent.

According to the SG (B) series OVDT products with its advanced performance standards and reliable safety such as low loss and noise, and small part discharge etc. It is widely used in the load center who required high fireproof safety and environmental protection, such as tour sight spot, commercial affairs center, shopping center, resident area, high-rise, airport, subway, hospital and wharf etc.

Feature:

1. Environmental protection:
High quality H grade insulation material is used the product, there is no emission of hazardous gases under high temperature.Owing to the opening winding, it is convenient to take copper back for recycling after the service life.
2. Reliable insulation system:
NOMEX paper and ET-90 series H grade resin is chosen as basic insulation system, optimized design makes insulation system 180 degrees centigrade - 220 degrees centigrade, which is safe, steady and reliable under high temperature.
3. Advanced processing technology:
Adopting VPI technology and curing process under the high temperature, the lacquer film is bright and even, no cracking, the partial discharge is less than 5PC, with low noise.
4. Overload capacity:
H grade Nomex paper is used for insulation of winding in opening structure. Its dissipation of heat is faster and temperature rise is even, which shows higher overload capability.
5. Stronger withstanding short-circuit capability:
VPI process is carried out for H. V. &L. V. Coils and pre-pressing device such as disc spring and silicon rubber is put on the end of coils to strengthen the mechanical strength for both coils and product, which improves its withstanding short-circuit capability.
6. Weatherproof:
The whole product is coated with H grade insulation lacquer twice. Lacquer film has the good adhesion, mechanical strength and insulation performance without cracking. Therefore, it is weatherproof such as moisture, fog and dust, particularly in serious pollution.
