Copper / Alloy Conductor

Rectangular busbar in high-purity electrolytic copper (>99.95%) or high-purity aluminum alloy, with optional full-length tin or silver plating.

DuPont Polyester Film Insulation

Double-layered per phase, up to six layers between phases — Class B insulation, 130°C heat resistance, >10,000V single-layer withstand voltage, non-toxic and halogen-free.

Precision Connector

Dual-head torque-retaining bolts and custom Belleville springs seat with a standard 19mm wrench; connector conductor cross-section exceeds 1.2x the busway body for low contact resistance.

Robust Enclosure

Single-step extruded aluminum-magnesium alloy — three times the thermal conductivity of a steel enclosure, with low-magnetic-permeability material that mitigates eddy-current and hysteresis losses.
