Electrical Stress Control Self-adhesive Tape

Electrical Stress Control Self-adhesive Tape

Product Description

Electrical Stress Control Self-adhesive Tape is a specialized conductive tape designed to manage and redistribute electrical stress in medium and high-voltage cable accessories. Composed of a semi-conductive polymer base (typically carbon-loaded EVA or rubber) with a consistent conductive adhesive layer, this tape ensures smooth control of electric field distribution at critical points such as cable terminations and joints. When applied over the insulation shield cut-off point, it prevents excessive electrical stress concentration that could lead to partial discharge or insulation breakdown. The tape's self-adhesive nature allows for easy and precise application, conforming perfectly to cable contours without requiring heat or special tools.

This tape is essential for maintaining the long-term reliability of power distribution systems, particularly in applications involving XLPE and EPR insulated cables. It is engineered to maintain stable conductive properties across a wide temperature range while resisting moisture, corrosion, and electrical aging. It is widely used in the construction of cable terminations, splices, and transition joints for utilities, industrial plants, and renewable energy projects.

Specification Model 

DYL-50

Product Dimensions

0.6*25*5000 (T×W×L)

Product Application

Used for stress control at cable joints and terminals, which can evenly distribute the electric field and reduce partial discharge. It is mainly used for bus - bar tubes and wrapped - type cable accessories (the wrapped - type is mainly for the overseas market). It is also applied in110kV/220kV intermediate joints in China.

Product Advantages

• Electric Field Optimization: The high dielectric constant characteristic makes the electric field more uniform.

• Good Flexibility: It can be used in a wide temperature range from -40℃ to 90℃, ensuring the stability of stress control effects.

• Strong Durability: Less likely to experience performance degradation, cracking, or deformation.

• Good Compatibility: It will not chemically react with or corrode the cable body.
