Hardware Fitting


In the fields of fittings for the substation and transmission line in this world, TCI will be always adapted to local conditions, well-aimed development and production of customer specific components.

The product portfolio includes:

◎ Suspension Clamp

◎ Tension Clamp

◎ Link Fittings

◎Protection Fittings, Guy Wire Fittings, Earthing Fittings, Insulator Fittings, etc...



Suspension Clamp


Suspension clamps are used to connect the conductors to the insulators.

The product range comprises products for all purposes. Some of the types have heliformed rods already integrated, whereas others can be used with or without such rods.

Besides the standard designs special slipping clamps, which allow slipping between two defined values, are available.





Tension Clamp


Tension clamps are used to tension conductors and earth wires and must

therefore satisfy the most stringent requirements.

There are two basic systems of tension clamps:

1. Detachable clamps, such as wedge-type tension clamps, thimbles, bolted type tension clamps, which allow for subsequent adjustment, and

2. Non-detachable clamps, such as compression dead-end clamps which require absolute matching to the conductor length.



Link Fitting


Link fitting is used to connect insulators to the towers and conductors.

The forged hardware is mainly made of heat treated steel.

This steel is especially suitable for forging and its good performance, especially ductility, is due to the heat treatment process.

This is of particular value if dynamic loads, for instance through ice shedding or oscillations, are likely.

In particular cases, where at very low temperatures dynamic stresses could occur, hardware made of special steels is available.


Protection Fittings & Guy Wire Fittings & Earthing Fittings


Protection fittings are used to restrain vibration of conductor and ground wire of overhead transmission lines, or to grade and to shield the insulator string of 330kv and above.

Guy wire fittings are used to connect guy wire of tower, mostly dead end tower and angle tower.

Earthing fittings are used to connect with the ground to take away the electricity to the ground such as grounding clamp and grounding rod.



up to now, TCI fittings have been equipped in more than 50 countries and areas, which were designed and produced strictly according to related IEC & ANSI standards.

At eye-level we will surprise you with the design of our fittings, which are often noticed as just a "small" part of a transmission line.

TCI fittings- the steady link of the whole power project!
