China Manufacture Resin Expoxy Support Insulator Bus Bar Insulator SM

Feature 

Grade A (copper nut is 1.5 times the thickness C grade copper nut, torque and tensile strength are C-level doubled For retardant please specify.)
Grade B (for iron nickel plated nut, torque and tensile strength is a double A-level, it is recommended to use)
Grade C (for the market is the most common thin copper nut, the price advantage, the proposed less stringent requirements for quality customers.)
