BIRKA’s new insulating crossarms are conceived and designed to prevent bird deaths by electrocution on overhead power distribution lines. The crossarms are made of fibreglass profiles with a dielectric strength of more than 10Kv/mm and high mechanical performance, manufactured with Dual Pull Braiding technology, forming a completely insulated structure. The new crossarms are designed and proved for the direct replacement of traditional metal crossarms, representing a revolution in the electrical distribution infrastructure market.
The main advantages of BIRKA’s crossarms are:
– The crossarm acts as a completely insulating structure, avoiding the electrocution of birds on the power lines and contributing effectively to the conservation of the biodiversity of the territory.
– There is an increase in the safety conditions of workers during the installation and maintenance of overhead distribution networks.
– The weight is reduced by more than 50% compared to traditional metal crossarms, facilitating their transport and installation, even in areas of difficult access.
– Maintenance costs due to metal corrosion are significantly reduced thanks to the nearly total elimination of metal parts, contributing to a greater durability and safety of the infrastructures.
