Screw type cable support is made of resin, glass fiber and filler by SMC process, which has many characteristics such as corrosion resistance, light specific gravity, strong electrical insulation, excellent fire resistance, long service life, etc.
Advantages of screw type cable support:
1. Natural insulation: the support has good insulation performance and does not need grounding itself. High quality resin and flame retardant materials have high arc resistance and PTI resistance.
2. Smooth surface: the friction coefficient is small, and the cable is free of abrasion damage.
3. Super corrosion resistance: no corrosion, rust and mildew in acid, alkali and salt environments.
4. Strong bending resistance: no creep. In humid, hot and cold environments, the mechanical strength remains above 95%, and it will not deform even under long-term load. Good mechanical strength can withstand more cables and achieve longer suspension distance.
5. Avoid eddy currents: the current flowing through the cable will generate a magnetic field, and the high insulation of the composite material will prevent the magnetic field from forming a closed loop with the support to generate circulation.
6. Lightweight and high strength, the weight is only 1/4 of the steel support and about 1/10 of the concrete support, so the construction is simple. Convenient for transportation;
7. Flame retardant and fireproof: heat resistant and cold resistant. Excellent fire resistance, good flame retardancy and burning speed (Grade I: 25, smoke density ≤ 500, oxygen index ≥ 29, safe and reliable for use in the range of - 40 to 150 ℃).
8. Super long service life: 50 years underground and 25 years above the ground, super long service life, durable, safe, environmentally friendly and non-toxic,
9. Environmental protection and anti-theft: FRP materials are safe, environmentally friendly, non-toxic, and have no recycling value, fundamentally solving the problem of theft.
Installation steps:
A set of supports includes fiberglass columns, corbels, pins (bolts) and polymer fixing caps, and the installation tools are ordinary electric drills, drills and wrenches.
1. Column installation: the positioning line on the back of the column is provided with a mounting hole with a hole diameter Ф 12.5. According to the installation construction drawing and the position of the column installation hole, use M12 expansion bolts to fix the column on the wall. A gasket must be installed between the bolt and the column. The trough column should be as close to the wall as possible.
2. Cable: drag the cable to the installation position of the cable bracket.
3. Installation of corbel: according to the requirements of corbel layer spacing, assembly holes have been reserved on the positioning lines on both sides of the column Ф 8.5； Fix the corbel on the trough column with bolts, and the bolts shall be properly tightened. Note that gaskets must be installed between the bolts and the column.
4. Cable positioning and fixation: place the cable on the support and bind it, and try to place the heaviest cable at the root of the corbel.
matters needing attention:
1. During installation, the cable support shall be close to the wall to prevent looseness.
2. It is forbidden to stand on the support or support other than cables.
3. When laying cables, it is forbidden to drop the cables from a high place, and they should be placed directly on the support.
4. During laying and maintenance, avoid pulling the cable on the support, and take effective measures to avoid the lateral force on the support.

Banan District Jianguo Building Materials Business Department mainly produces Chongqing well covers, composite material well covers, ductile iron well covers, stainless steel well covers, composite material well cover water grates, ductile iron well cover water grates, stainless steel well cover water grates, composite cable supports, etc., which are widely used in inspection well covers, water grates, communications, tap water, natural gas, electricity, chemical bases, etc Handhole cover plate. The product has the advantages of reasonable design, light weight, coloring, etc., which brings great convenience to installation, maintenance, and identification. At the same time, because the product has no recycling value, it fundamentally solves the danger of theft to pedestrians and vehicles.
