Safety requirements and test standards

1 inspection of insulators

2 Definition: resistivity above 108 /CM.

3 commonly used insulators

A.PVC (polyvinyl chloride)

B.SR-PVC (semi rigid PVC)

C.PP (polypropylene)

D.LD-PE (low density polyethylene)

E.HD-PE (high density polyethylene)

F.FM-PE (foamed polyethylene

Two, the extension rate of insulation

The rate of elongation depends on:

A, the material itself             B, out of the temperature             C, cooling way

D, conductor preheating, mask size, water cooling, e "UL" safety of requirements
