The function and performance of Stress Control Tube

The general substrate of Stress Control Tube is polar polymer, and then the filler with high dielectric constant is added. The Stress Control Tube is different from the insulation tube and other parts. The purpose of the insulation tube is to insulate and seal. Through the above content, we know that the function of the Stress Control Tube is to control and disperse the stress. The length of the Stress Control Tube is shorter than that of the insulation tube.

In order to make the cable run reliably, the Stress Control Tube is very important in the production of the cable head. The Stress Control Tube can achieve the effect of dispersing the electrical stress on the basis of not destroying the main insulating layer.

The power line stripped of the shielding core wire is concentrated at the shielding layer fracture. Then the shielding layer at the break is the most vulnerable part of the cable breakdown. Shielding layer of cable are most likely to breakdown, fracture, we take the scattered the focus (electric stress) of power lines, with the dielectric constant of 20 ~ 30, volume resistivity of 108 ~ 1012Ω·cm material electric stress control tube (hereinafter referred to as stress control tube), set in shielding layer fracture place, to spread the fracture of the electric field stress (power), ensure that cable can reliable operation.
