To provide stress relief of the electric field in all MV cables joints and termination for Heat shrink and Cold shrink technologies.
see image of the application below
This figure shows a MV cable termination when stress control mastic is applied. Stress control is provided in MV cable termination to control the high stresses, which exist at the area where the shield is terminated. The stress control mastic help to equilibrate the electrical field and reduce considerable the electrical stress. There is no concentration of equipotential lines, the electrical field is balanced along the termination.
The stress control system is designed for estimated life times longer than 30 years of service.
This figure shows the stress concentration at the end of the screen of MV cables termination when no stress control mastic is applied. The edge of the outer conductive layer is a critical point. The field along the dielectric/ air interface provides the highest electrical stress. It can induce electrical discharges in the insulation and the life of the termination would be limited depending on the stress at the end of the shield and the discharge resistance of the primary dielectric.
Storage
The product is supplied as plates or stripes of specified dimensions with antisticking paper on both sides. The product should be stored in the original packaging, protected from the dust, moisture, heat and sunlight. We recommend long duration storage of the product between + 15 °C and 30 °C
