Heatshrinkable Stress Control Sleeves

In medium-voltage cable preparation, the moment you strip back the metallic screen, you create a "stress point"—a concentrated electrical field that can lead to corona discharge and eventual insulation failure. BRENT Stress Control Sleeves are the invisible workhorses of the power grid, specifically engineered to smooth out these electrical gradients and ensure your terminations last for decades, not days.

Why Stress Control is Non-Negotiable

When you cut a cable screen, the electrical stress lines bunch up at that sharp edge. Without a control sleeve, the air around that point ionizes, leading to tracking and catastrophic breakdown.

Our sleeves use high-permittivity (High-K) material technology to:

Relieve Electrical Tension: By "spreading" the equipotential lines over a longer surface area, the sleeve prevents the high-voltage stress from concentrating at the screen cut-back.

Eliminate Discharge: Designed to keep the electrical field well below the ionization level of air, effectively silencing partial discharge (PD).

Provide a Seamless Interface: The sleeve’s unique impedance characteristics ensure a smooth transition from the cable’s internal insulation to the termination surface.

Built for the Technician, Engineered for the Grid

High-Permittivity Matrix: Formulated with precision-engineered fillers that provide the exact capacitive properties needed for 11 kV, 22 kV, and 33 kV systems.

Compact Profile: Unlike bulky traditional methods, these heat-shrink sleeves provide a slim, low-profile finish that fits easily into tight switchgear and transformer boxes.

Thermal Stability: Stays electrically stable even during heavy load cycles and high-temperature surges.

Tough but Flexible: The cross-linked polyolefin base is rugged enough to handle rough installation environments without losing its electrical properties.
