advantages:

1) High strength, light weight, the weight is only 1 / 4 of steel brackets and 1/10 of concrete brackets. So it's convenient for transportation, and construction.

2) Smooth finish and small friction factor help these brackets not to damage the cable.

3) These brackets are entirely insulated, which terminated the electric-erosion, and reduces damages caused by eddy current.

4) The brackets are water resistant which can be used for long-term in moist and watery conditions.

5) The brackets are heat and cold resistant and fire resistant which help them to be used under temperature of -50 - 130 degree centigrade.

6) Anti-chemical-corrosion, rust free, long service life (over 50 year), maintenance-free all make the brackets ideal for saving money on wiring projects.

7) Anti-burglary.

8)Not like steel brackets, these brackets are entirely insulated, so no earthing system is needed. This reduces a great percentage of mounting work, reduces a lot of labor cost.
