FRP Cable Bracket

LANDYOUNG FRP cable bracket is a composite material profile made of E-glassfiber, resin by SMC process.

The effect of using the FRP cable bracket is roughly as follows:

1. Make the cable layout neat and easy to maintain.

2. Raise the cables in layers and keep a certain interval to facilitate heat dissipation.

3. Various cables can be laid separately to avoid mutual influence, such as separate laying of control cables and power cables, and separate laying of high-voltage cables and low-voltage cables.

4. Use the cable bracket to hold up the cable to avoid flooding, mechanical damage, etc.

The angle steel cable bracket is the cable bracket with the longest history in the power system. Because of its high strength, it can be applied to various occasions, and the manufacturing is relatively simple and convenient. Therefore, the cable brackets used in the general old power plants and substations are basically They are all angle steel cable brackets. The shortcomings of angle steel cable brackets are: the steel consumption is relatively large. Under many harsh environmental conditions, such as subways, tunnels, chemical enterprises, rainy and humid or coastal salt fog, etc., the use of angle steel cable brackets is very easy to rust, regardless of whether it is galvanized or not. Galvanizing can only delay corrosion for about one year, and the cost of equipment protection is high, and the service life is short.

Advantages and features

•Smooth surface: small friction coefficient, no scratch damage to the cable.

•Corrosion resistance: no corrosion, no rust, no mildew in acid, alkali, salt, rainy environment.

•Strong flexural resistance: no creep, the mechanical strength remains above 95% in humid, high-heat, and high-cold environments, and does not deform even under long-term load. Good mechanical strength can withstand more cables and achieve longer Hanging distance.

•Natural insulation: The support has good insulation performance, and it does not need to be grounded. The high-quality resin and the high insulation of the flame-retardant composite material prevent the magnetic field and the support from forming a closed loop to generate circulation.

•Lightweight and high-strength, the weight is only 1/4 of the steel bracket and about 1/10 of the concrete bracket, and the construction is simple and convenient. Easy to transport;

•Flame-retardant and fire-resistant: heat-resistant and cold-resistant. Excellent fire resistance, good flame retardancy, burning speed (level 25, smoke density less than or equal to 500, oxygen index reaching more than 29, can be used in the range of -40 to 150 degrees Celsius, safe and reliable).

•Long service life: 50 years underground, 25 years above ground, long life, durable, safe, environmentally friendly, non-toxic,

•Environmental protection and anti-theft: FRP materials are safe, environmentally friendly, non-toxic, and have no recycling value, which fundamentally solves the problem of theft.

Application

Applicate for power plants, power cable trenches,telecommunications cable trenches, subway tunnels, chemical companies, rainy and humid or coastal salt fog and other cable laying places.
