 Yuansheng composite cable holder of the technical characteristics: 
 1, the unique structure: products of national patents, the unique mechanical structure gives great support bracket. 
 2, high strength: a unique structural design of the cable bracket has good mechanical strength, can withstand more cables, suspended for longer distance, not even in the long-term deformation under load. 
 3, light weight: density is about 1.9, only the carbon of the 1 / 4, but the tensile strength is close to or even more than carbon steel, the same strength requirements of the composite cable holder has a lighter weight. 
 4, strong corrosion resistance: in acid, alkali and salt corrosion environment will, no rust, no mold borers. 
 5, fire performance: a good flame retardant properties, as needed, the oxygen index can reach 80 or more. 
 6, insulation: current flowing through the cable process will produce a magnetic field, the magnetic field generated and the frame form a closed loop circulation of the cable temperature, current loss increased, and further the circulation temperature, may create a strong arc and damage to power cables , Yuen Shing high insulation properties of the composite generation of complete elimination of circulation, protect the power cable. 
 7, environmental security: A new composite materials, safety and environmental protection non-toxic, light and materials and the recycling value, to solve the metal cable support from the major, easily stolen and other problems. 
 8, long life: 50 years underground, the ground for 30 years, long life and durability.
