Construction and Insulation
The core and coil is fully encapsulated in epoxy resin in a complete vacuum process. This strict casting procedure results in high dielectric Strength and mechanical strength. We choose raw materials with excellent electrical and mechanical performance. Our voltage transformer is able to withstand wide temperature range. They are low water absorption, fire resistant, free to oil, non-toxic and explosion proof and so on.
Various Types of Our Voltage Transformers
Our voltage transformers are available in different sizes and grade.
We mainly have the following voltage transformers:
Fully enclosed voltage transformer
Semi-enclosed voltage transformer
Fused voltage transformer
Parts for V connection voltage transformer
Plateau-type voltage transformer
Our current transformers are widely used in power distribution stations of high-rise buildings, airports, stations, wharfs, subways, factories, and oil-fields and so on.
Our voltage transformers require no maintenance. Only occasional cleaning is needed if installed where air contamination is severe.
We are 100% sure that we are able to deliver the goods in time, for we have powerfull production capability.
