BLMT Terminal Bocks

BLMT Terminal Blocks (Shear-Bolt Mechanical Lugs) are high-performance aluminium cable terminals designed for reliable connection of copper/aluminium conductors to electrical equipment, busbars and power distribution systems. Featuring torque-calibrated shear-head bolts and tin-plated aluminium body, they ensure consistent clamping force, low contact resistance, and quick installation without crimping tools for medium-voltage (up to 84kV) indoor/outdoor applications.

Key Features

• ✅ No Crimping Required: Install with standard wrench only; no special tools

• ✅ Shear-Bolt Design: Pre-set torque bolts break at exact tension for safe, consistent connection

• ✅ High Conductivity: Tin-plated high-strength aluminium alloy, low contact resistance

• ✅ Wide Conductor Range: Covers 16–1500 mm² with single-model coverage

• ✅ Cu-Al Compatible: Safely connects copper to aluminium conductors

• ✅ Voltage Rating: Suitable for 1kV–84kV medium/low voltage systems

• ✅ Weatherproof: Sealed design with anti-corrosion lubricant for outdoor use

• ✅ Vibration Resistant: Tooth-shaped inner wall prevents loosening
