TE Connectivity’s (TE) mechanical connectors and repair sleeves products consist of a tin-plated body, shear head bolts and inserts for small conductor sizes. 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.

Connectors 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.

Before using mechanical connectors in cable accessories, confirm that they are suitable for the given application and if necessary consult our experts.

  1. How to Properly Cut a Cable When Installing a Connector (English)

When installing the connector of a MV joint, make sure the conductor is entirely inserted in the connector: there is no space between cable insulation and connector. Otherwise, remove conductor from connector and cut to correct size.
