SAFE. RELIABLE. EFFECTIVE.
BRENT heavy-duty Heatshrinkable 3 core Breakouts are engineered to provide a robust, watertight seal at the junction where a multi-core cable splits into individual cores. Designed for medium-voltage applications, these components ensure long-term mechanical protection and electrical insulation in the most demanding environments.
Superior Environmental Sealing: The internal surface is coated with a high-performance hot-melt adhesive that melts during shrinkage, filling voids and preventing the ingress of moisture, dust, and contaminants.
High Mechanical Strength: Manufactured from cross-linked polyolefin, these breakouts offer excellent resistance to abrasion, impact, and UV radiation.
Flame Retardant & Chemical Resistant: Built to withstand exposure to common solvents, acids, and alkalis, making them ideal for industrial and underground installations.
