Some advantages of using composites in the electrical industry
High strength to weight ratio
Excellent thermal and chemical resistance
to corrosive environments such as seafront, ports and high-rise areas
as electrical and thermal insulation
with radio waves
Reduced power loss
by preventing electrical leakage from line to pole
Economical and low cost
of transportation, installation and maintenance.
and no need for heavy machinery
Up to now, the poles and cross-linking arms have been made from wood, concrete and steel. Nowadays, in advanced countries, instead of the old ones, fiberglass poles are used because of their great advantages. Although the initial cost of fiberglass composites is higher than metal, concrete and wood materials, reducing the cost of installation, services, maintenance and resistance to corrosion are all that make the composites occupy a special place in the electrical transition line industry.fiberglass poles with one-third weight of the wooden poles, half weight of the steel poles, and only one-tenth of the concrete foundation poles weights are a very attractive choice for most power companies.
One of the applications of fiberglass composites in the power industry is the construction of pipes for cableways and energy tunnels. GRP pipes can be used in combination with special fittings and accessories to form a multi-layered, multi-row cable system. These pipes are used for urban power network cables and under–ground telecommunication cables.
