Natural Gas Safety Valve (Socket)

Hot deformation test is also called a hot pressure test is an acceptance test in order to assess high-temperature resistance of the material to deformation. Thermoplastics tend to deform under high temperatures and small damage during movement or under installation to cable, can cause a puncture or cut of insulation. This could result in the circuit break down shutting down the entire system.
According to the famous test institute of Germany, it was said that the most failing test for HO5-HO7V K cables is this test. In order to achieve a high speed of extrusion, manufacturers tend to inadvertently ignore the impact of compound degradation.
