Overhead line equipment - application

This is a special category of products used to build and maintain overhead power lines – those designed to transmit electricity. They constitute the majority of existing transmission lines. An overhead line runs through vast areas, which exposes it to the effects of destructive atmospheric, topographic and environmental factors that must be taken into account at the design, construction and operation stages. The insulation here is air. Dedicated line equipment supports the reliable and safe operation of the power grid – of course, provided that rigorous standards and technical requirements are met.

Elements classified as overhead line equipment

Overhead line accessories include a wide range of elements such as: • insulators – they ensure the isolation of wires from supporting structures, allowing for loss-free power transmission; • terminals and connectors – they are used to connect wires and mount them to supporting structures; • covers – they protect wires against mechanical damage and the destructive effects of atmospheric factors; • transmission wires – they are responsible for the transmission of electricity (the material used depends on the requirements that a given low-voltage overhead line should meet); • disconnectors – they enable the disconnection and connection of wires in order to safely carry out electrical work; • transformers – they are used to modify the voltage in the network; • cables – they enable the connection of insulators, connectors, transmission cables and other line elements, and are made of various materials, such as stainless steel or aluminum. It should be remembered that low-voltage and medium-voltage overhead line accessories are two different product categories. Low-voltage power networks are those up to 1000 V.
