MECHANICAL CONNECTORS, SHEAR BOLT CONNECTOR
Features
1.Mechanical connectors designed to connect two MV conductors inline without the need for crimping.
2.High tensile tin plated aluminium alloy.
3.Solid moisture block between conductors.
4.Conductor size based on circular stranded copper and aluminium.
5.Torque-controlled shear-head bolts guarantee a good electrical contact.
6.Easy installation with standard socket spanner.
Mechanical connectors and repair sleeves are designed for use in low and medium voltage applications. Only three sizes cover conductor sizes from 25 mm² to 400 mm². All products consist of a tin-plated body, shear-head bolts and inserts for small conductor sizes.
Repair sleeves made of special aluminium alloy, these contact bolts are double shear head bolts 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.
Repair sleeves are chamfered at the edges and available with or without oil barrier (as blocked and unblocked types) depending on the application requirements. The bolted fitting featured herein was developed specifically for use in medium voltage cable accessories up to 42 kV. They may also be used in the 1 kV range.
LOW VOLTAGE and MEDIUM VOLTAGE electrical cable connections, including cable SPLICES AND TERMINATIONS, have historically been made using an infinite array of compression connectors and the OEM and/or UL approved appropriate tools.
CROP introduced a new style connector called SHEAR-BOLT several years ago, and the product line is growing in inventory, and with our key manufacturers of MV Cable terminations, splices and TEE-Bodies.
