Product Overview


The BLMT series Tin-Plated Mechanical Aluminium Alloy Lug is an innovative cable termination solution for medium-voltage (10kV-35kV) systems. It connects copper cables, aluminium cables, or aluminium alloy cables to aluminium terminals of electrical equipment (e.g., transformers, switchgears). The lug body is made of high-strength aluminium alloy, with a tin-plated surface to enhance anti-oxidation and corrosion resistance. It supports conductor cross-sections from 25 mm² to 300 mm², with models including BLMT-25/95, BLMT-35/150, BLMT-95/240, and BLMT-120/300.


Core Features


Tool-Free Installation: No specialized crimping tools are needed – only a socket spanner or wrench suffices, simplifying on-site operations and reducing reliance on professional skills.

Torque-Shear Bolts: Built-in torque-controlled bolts break at preset values, ensuring consistent clamping force and reliable electrical contact, avoiding issues from over-tightening or under-tightening.

Moisture-Proof Solid Palm: The one-piece solid palm structure blocks moisture, dust, and corrosive gases from entering the connection point, extending service life in outdoor or harsh industrial environments.

Pre-Filled Jointing Compound: High-performance compound is pre-filled to enhance conductivity, resist oxidation, and provide extra environmental protection.

Multi-Cable Compatibility: Works with copper, aluminium, and aluminium alloy cables, reducing inventory costs for projects that use multiple cable types.


Scenario-Based Solutions


Medium-Voltage Substation Equipment: In 35kV substations, the BLMT-95/240 (95-240 mm²) connects transformers and circuit breakers to power cables, ensuring stable power transmission between equipment.

Renewable Energy Stations: For wind farms or solar parks, the BLMT-35/150 (35-150 mm²) links photovoltaic inverters/wind turbines to the grid, withstanding -40°C to +70°C temperature variations and UV radiation.

Industrial Motor Wiring: In steel mills or chemical plants, the BLMT-120/300 (120-300 mm²) connects large-capacity motors, resisting vibration from heavy machinery and conductive dust.

Urban MV Grid Upgrades: When renovating old urban MV grids, the BLMT-25/95 (25-95 mm²) replaces outdated crimping lugs, cutting installation time and improving connection reliability.


Technical Support & Services


Size Customization: We adjust cable cross-section compatibility, terminal hole diameters (φ13/φ17/φ21), or bolt quantities to match unique equipment needs.

Installation Training: On-site or online training covers bolt tightening, torque verification, and quality inspection to ensure standard operations.

Certifications: Each batch includes test reports (conductivity, corrosion resistance) complying with IEC 61238 standards.

After-Sales Maintenance: A 3-year warranty is provided. Technical support is available within 48 hours (domestic) or 72 hours (international) for issues.
