Recently a customer high-voltage cable damage later consulting us, after investigation, found that because the high-voltage cable is most likely to penetrate the shield fracture, we take to disperse this concentration of power lines, with a dielectric constant of 20-30, the material made of electric stress control tube, set in the shield fracture, to disperse the fracture of the electric field stress.
Ensure that the high-voltage cable can run reliably. Stress pipes are very important for the reliable operation of cables.
