The BT Series T-Type Resin Cable Joint, manufactured by Borna Electronics, is designed for creating branch connections perpendicular to the main cable route in low-voltage power distribution systems. Its T-shaped configuration enables reliable cable branching while maintaining excellent electrical insulation and mechanical protection.
Manufactured using high-quality polyurethane resin with superior dielectric properties, the BT Series provides a durable, moisture-resistant, and long-lasting connection suitable for a wide range of environmental conditions. The transparent impact-resistant mold allows visual inspection of the cable connection before resin casting, ensuring installation accuracy and reliability.
With its compact design, fast assembly process, and excellent resistance to moisture, chemicals, alkaline soil elements, and UV radiation, the BT Series is an ideal solution for underground and above-ground low-voltage cable networks.
