1.stay insulator with ISO9001 certificate,good quality,made of porcelain and smart design. 2.ANSI safe standard

porcelain  low voltage busbar Stay Insulator:

The required performance values for the stay insulators are given below:• Minimum Mechanical Failing Load : 42 kN• Minimum wet power frequency flashover Voltage : 12kV• Minimum dry power frequency flashover Voltage : 25 kVMinimum leakage distance :41mm

The holes in the insulator to be smoothly radiused with as large a radius as practicable to present an even bearing surface to the stay strand loop.
