Product Characteristics
1.The product is used in subway grounding protection system, ac bus or DC bus overvoltage protection; It can also be used as brake resistance or energy-absorbing resistance of large equipment
2.Packaging: welding, insert
3Feature: low resistance, extra high power, excellent ability absorb energy in short time
Product Features
1.It has good weldability performance, between the resistive element sheet-language films, the connecting point use resistance spot welding, non-contact resistance, strong,durable beautiful.
2.The resistor's value is stable, has a resistance - temperature complementary characteristics, the error of the total resistance value is smaller than the original old models (error does not exceed ± 7.5%).
3.Durable, long life
4.The resistance material is 304L stainless steel, not easy to rust. Can be used in harsh environments
