Frequently Asked Questions

What does the model name "U40B" represent?
"U" stands for Disc Suspension Insulator, "40" indicates a rated mechanical failing load of 40kN, and "B" signifies the Ball and Socket connection type.
What material is used for the insulator's dielectric part?
The dielectric is made of high-quality toughened glass, chosen for its excellent electrical and mechanical properties.
Can this insulator be used in heavily polluted environments?
Yes, for high-pollution areas, it is strongly recommended to use a sacrificial zinc sleeve on the pin for enhanced anti-corrosion protection.
What standards do these insulators comply with?
They are manufactured in accordance with IEC60383-1, GB/T1001.1 for product models, and IEC60120/BS 3288 for connection structures.
What is the standard locking pin provided?
Unless special instructions are provided by the customer, an R-pin is the standard locking device used for the U40B model.
What is the mechanical capacity of the U40B?
The U40B has a rated mechanical failing load of 40kN, which is approximately equivalent to 4 tons.
