Electrical composite glass fiber crossarm is a structural component used in various industries and applications.
It is composed of glass fiber and resin, which are bonded together to form a sturdy and durable material.
Fiberglass composite cross arms are typically designed in a cross shape, with multiple arms extending in different directions.
They are used to support and distribute loads in power transmission and distribution systems.
The lightweight and sturdy properties of glass fiber composite materials make them an ideal choice for this application.
