Tech Info: Transmission Line Hardware

McWade Productions manufactures and supplies a comprehensive range of hardware fittings utilised in the make-up of complete insulator string sets for both LV/HV transmission lines and substations up to an operational voltage of 800kV.

All forged steel hot dipped galvanised fittings are manufactured in compliance with IEC specification number IEC120.

The catalogued range of compression connectors provides for service and heavy duty “T” connections from Main Lines. Connectors are available for COPPER ALUMINIUM and BI METAL interconnections between Main Line conductors and branch cable. Live Line bails are included in the range, since these provide for disconnectable features at Overhead Line section points, or any situation where live clamp tapping of the conductor is desirable.

The types of connector designs available ensure the complete requirements of HV and LV tapping are catered for with a minimum number of “Range Taking” compressed with the “Bimetal 4” No Die Crimping Tool.

Accessory equipment such as:

• Tensioning Machines
• Lifting Apparatus
• Hot Line Working Tools
• Grounding/Earthing Equipment
• Cover up equipment
• Working Platforms
• etc. are sourced from both local and internationally recognised suppliers.
