BSM mechanical connectors and repair sleeves are designed for use in medium voltage cable accessories up to 42 kV. They may also beused in the l kV range.They cover conductors sizes ranging from 10mm² to 1500 mm².
BSM connectors consist of a tin-plated body,shear bolt heads and inserts for small conductor sizes.
Made of High-strength special aluminum alloy, these contact bolts are double shear bolt heads with hexagon heads. The bolts are treated with a highly lubricating agent. Contact bolts are irremovable once their heads have been sheared off. The lug body is made of a high-tensile, tin-plated aluminium alloy. The internal surface of the conductor holes are grooved.
