Composite pultruded cable bracket is polymer composites material which is composed of resin, glass fiber and filler. It is characterized by light weight, corrosion resistance, electrical insulation, fire performance, long service life. Generally, people will usually call is as FRP cable support bracket, composite cable bracket, fiberglass pultruded cable insulation bracket, etc.
Composite pultruded cable bracket is combined, and it is composed of cable bracket, column and fixed pin. Column and the pin of the material is made of glass fiber reinforced plastic composite materials by high temperature, the column can be according to the needs of the interception of any length, height adjustment, free assembly, cable bracket has a variety of specifications to choose from, to meet the requirements of different length and loads.
