automatic fabric wrapping machine supply has good physical and mechanical properties and excellent insulation properties. automatic fabric wrapping machine supply grade What is the grade?

According to the level of voltage resistance, rubber insulation board can usually be divided into 5 grades, respectively, Y, Y1, Y2, Y3 and Y4 grades.

Lv. Y

Y-grade rubber insulating board is a commonly used insulating material, its standard resistance voltage is 6KV, suitable for low-voltage electrical equipment electronic components, instruments, mechanical parts and insulation gaskets.

Y1 grade

The standard resistance voltage of Y1 grade rubber insulation board is 10KV, which is more widely used than Y grade, and can be used as insulation material for generator windings, switchgear, cable terminals and other high-voltage equipment.

Y2 grade

Y2 grade rubber insulation board is a kind of high voltage insulation material, its standard resistance voltage is 20KV, usually used in generator windings, cable terminals, transformers and other high voltage electrical equipment.

Y3 grade

The standard resistance voltage of Y3 grade rubber insulation board is 35KV, which is a high-performance material used for the insulation of UHV electrical equipment, and is widely used in the insulation and sealing fields of UHV equipment such as substations.

Y4 grade

Y4 grade rubber insulation board is the highest grade of insulation material on the market at present, and its standard resistance voltage can reach 220KV, which is mainly used in the insulation and sealing fields of ultra-high voltage power equipment.
