In order to ensure the safety of power supply and the city's increasingly demanding beauty, cable brackets have begun to be widely used. At the beginning, the brackets made of angle iron have been used to erect cables. It can be seen that the energy consumption is relatively large, and the quality is difficult to guarantee. At the same time, The angle iron bracket has a fatal disadvantage, that is, it is particularly easy to corrode. Interestingly, it is used in humid environments such as tunnels and subways. It is more troublesome to maintain, and the service life of this kind of bracket is too short. People have used paint or hot-dip galvanizing on the outside of the angle iron bracket, but it cannot solve the fundamental problem, cannot guarantee the safety of the facility, and seriously affects the electricity.
With the continuous development of economy and the continuous advancement of science and technology, people have developed the use of composite cable brackets, which can easily overcome the weaknesses of angle iron brackets. Due to its special material, it has good corrosion resistance and anti-corrosion performance. The static flame retardancy is also good, and the installation is relatively simple, which shows that it is suitable for various environmental conditions.
1. The model of the cable bracket should be determined according to the specific situation. Generally, there are two models, some can be placed three cables, and some are suitable for two. If there are more special requirements, of course, it can also be customized.
2. The cable support should be installed horizontally. If it is necessary to tilt, then other measures must be taken to fix the cable. And it requires balance and verticality.
3. The use of the cable support should be within the specified temperature range, the highest temperature should not exceed +70°, and it should not be lower than -20°.
4. Once the bracket needs to be pre-embedded before using it, attention must be paid to the construction. It must be firm and dense, and at right angles to the wall, without distortion.
The glass fiber reinforced plastic cable support adopts SMC manufacturing process. The full name of SMC in English is Sheet Mould Compound. It is a sheet-shaped unsaturated polyester reinforced molding compound made of resin paste impregnated with glass fiber. It is GF (glass fiber), UP (unsaturated resin), MD (filler) and low Shorten the flake molding compound composed of various additives. SMC glass fiber reinforced plastic cable bracket is a kind of thermosetting composite material. It is made up of SMC composite materials that are restricted at high temperatures. The selected alkali-free glass fiber R2O content is less than 0.8%, which is an aluminoborosilicate component. Its chemical stability, electrical insulation function, and strength are all excellent, and it is mainly used as electrical insulation materials and reinforced materials for glass fiber reinforced plastics.
SMC cable bracket has excellent electrical functions and corrosion resistance, light weight and high strength, simple and flexible engineering design, and its mechanical function can be comparable to some metal materials. The surface finish of the obtained product is high. The appearance quality is better after selecting low shortening additives. ideal.
1. Natural insulation: the support has good insulation function, it does not need to be grounded, the excellent resin is equipped with flame-retardant materials, and the arc resistance and tracking index (PTI) are high.
2. Surface lubrication: The friction coefficient is small, and the cable has no damage from scratches.
3. Super corrosion resistance: no corrosion, corrosion and mildew in acid, alkali and salt environment.
4. Strong bending resistance: no creep, in humid, high heat, and cold environments, the mechanical strength remains above 95%, even under long-term load, it will not deform, and the outstanding mechanical strength can accept more cables and complete longer The dangling interval.
5. Prevention of eddy current: magnetic field will be generated when current flows through the cable, and the high insulation of the composite material prevents the magnetic field and the bracket from forming a closed loop and circulating current.
6. Lightweight and high-strength, the weight is only about 1/4 of the steel bracket and 1/10 of the concrete bracket, and the construction is simple and convenient. Easy to transport;
7. Flame-retardant and fire-resistant: heat-resistant and cold-resistant. Excellent fire protection function, good flame retardant function, 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).
8. Super long life: 50 years underground, 25 years above ground, super long life, durable, safe and environmentally friendly, non-toxic,
9. Environmental protection and anti-theft: FRP materials are safe, environmentally friendly, non-toxic, and have no recovery value, which fundamentally solves the problem of theft.
