Product introduction

A.transformer (with chassis)

Produced DG (B) / SG (B) series single the, coherent three isolation transformer Over the years the company has specialized in the production of high-quality materials and advanced technology, low-voltage transformer capacity with reference to the latest research and development of similar foreign products from 1KVA to 2500KVA between their appearance and installation dimensions have been standardized, processing according to customer requirements.
    The products, self-cooled and air-cooled air, some of the special requirements of customers, such as water-cooled. The product has a small size, light weight, high thermal insulation level, customers, according to the bare metal products with protective shell or outside the box.
    DG / SG series dry type isolation transformer with imports of high-quality cold-rolled silicon steel sheet pillar core, joins us according to the practical requirements of the customers, reasonable structure, good performance, high efficiency and low noise. Original, pay coil good insulation and isolation, to pay the edge of the circuit from the power grid and outside interference of high-frequency electromagnetic waves.
     The product is suitable for AC 50Hz/60Hz, voltage 3000V following a variety of industrial equipment corresponding to the power distribution unit circuit.
Core material: transformer core material silicon steel sheet, the quality of the quality and efficiency of transformers with silicon steel sheet has a great relationship. The company selected silicon steel sheets are high-performance silicon steel sheet.

Product Features:
1), the use of high-performance silicon steel sheet, system stability and reliability, low loss;
2), the primary and secondary windings of electrical completely isolated, remove the harmonic number of customer targeted by the connection and the design parameters, according to the requirements of the design of anti-interference ability;
3), the coil overall VPI vacuum pressure impregnation, and then the high-temperature curing dry, the film is bright and uniform, do not crack, PD ≤ 5pc;
4), flame retardant, flame retardant, non-toxic, self-extinguishing, fire. In the high-temperature fire burning, almost no smoke;
5), film adhesion, high mechanical strength, has excellent resistance to moisture, salt spray, dust capacity, suitable to run in the severe pollution of the environment;
6), the insulating layer is extremely thin and uniform, short-time overload capacity is very strong, without forced cooling. 120% of the long-term overload 140% overload 3 hours;
7), this series of products, low noise, with the flow, overload protection, applicable load range can withstand instantaneous overload, long-term continuous work.
