4x25mm2 Aerial Bundled Cable For Overhead Transmission Line
Product Description
Aerial bundle cable: overhead lines are mostly manufactured in accordance with French standards, of course, they can also be manufactured in accordance with national standards. Now they are mainly used abroad.
High-voltage transmission is generally carried out underground in cities with insulated cables and is often transmitted in the field by overhead lines carried by towers
The messenger conductor can be of galvanised steel wire also.
The purpose of messenger wire is
A) It acts as load bearing wire.
B) It acts as earth or neutral conductor.
To be used at cotages of 600V phase-to-phase or less and at conductor temperatures not
to exceed 75oC for polyethylene insulated conductors or 90oC for crossliked
polyethylene(XLPE) insulated conductors.
