High tensile strength U channel used in power rigid

High Tensile Strength Custom U Channel With Excellent Track Resistance 1

power rigid also known as is used extensilvely in power rigid,Transmission and distribution includes two concepts, they are transmission and distribution .Transmission refers to the transmission of large amounts of electricity from power plants or power generation centers to the consumption area of electricity, or the transmission of power for each other between different power channels;
Power distribution is the distribution method which distribution to users in the consumption power area ,it was serviced for user service directly.
In the transmission and distribution which including the reactor, transformer, switch cabinet, circuit breaker, UPS uninterruptible power supply, laminated bus, etc.;Our upgm203 sheet are widely used in this field,we have accumulated rich experiences of material application and R&D.
