Order Tel: 18730853086 Yu Cheng new FRP composite material cable holder, also known as FRP cable bracket, composite cable bracket, cable channel cable bracket, composite cable bracket, the polymer composites, namely resin, glass fiber and filler by SMC pressing process made with corrosion-resistant, light weight, high electrical insulation properties, many features excellent fire performance and long life. First, Yu Cheng new FRP cable bracket Background: In recent years, China has invested heavily in the transformation of urban and rural power grids, but the Old Town earlier distribution line construction period, construction standards and demand is relatively low compared to the modern, serious aging equipment, a large number of Like wire spider web hanging in the air, not only impede the urban visual impact, but also buried many security risks, serious harm to the public safety. In such an environment, the city can be enhanced grid reliability and a strategic line transmission capacity, and eradicate the visual pollution and beautify the urban environment development perspective, national ministries proposed the "cable into the ground," the general requirements, cable tunnels and cable Ditch the city has become the main channel power. With the full standardization of grid infrastructure, standardized development, and adapt to the trend Shimoji cable engineering, high-quality cable support the development and selection of an important issue we face. Second, Yu Cheng traditional angle iron brackets problems: Over the years, the production of cable support materials including metal cable bracket angle iron, cement and other cable bracket, because metal stents made of steel or angle iron roll forming simple, economical, and easy get features, so angle iron cable bracket in a long time has been used as a domain laying power cables primary election supplies, but during use, angle iron bracket material weakness has become increasingly prominent: 1, cable and metal vortex action to produce electricity loss , accounting for more than 50% of the cable iron loss; 2, easy to rust susceptible to corrosion, rust and heat zinc were also unable to avoid the technical processing, low life; 3, in the subways, tunnels, chemical industry, damp or coastal limited use under harsh environmental conditions, salt spray and other occasions; 4, the production process energy consumption, process, long cycle. Third, the advantages of the new Yu Cheng FRP cable bracket of the new FRP cable bracket using the SMC production process. SMC English called Sheet Mould Compound, is a chip made of resin impregnated fiberglass burnt unsaturated polyester reinforced plastic mold for GF (glass fiber), UP (unsaturated resin), MD (filler) and low shrink additive sheet molding material composed of a variety of additives. SMC FRP cable bracket is a thermoset composites. SMC composites consisting pressed at high temperatures. Selection of E-glass fiber R2O content is less than 0.8%, is an aluminum borosilicate ingredients. Its chemical stability, electrical insulation properties, strength are good, mainly used for electrical insulation and fiberglass reinforced materials. In short, SMC cable support with excellent electrical performance and corrosion resistance, light weight, high strength, easy engineering, flexible, and its mechanical properties can be comparable with some of the metal material, the resulting product surface finish, low profile additives, the appearance quality even better. 1, the natural insulation: Good insulation bracket itself without grounding, quality resins with flame-retardant materials, arc resistance properties and resistance to tracking index (PTI) high. 2, the surface is smooth: the friction coefficient is small, cable-free Ge abrasion damage. 3, ultra-resistant: acid, alkali, salt environment corrosion, rust, mildew borers. 4, bending and strong: no creep in the wet, heat, cold environment, the mechanical strength to maintain more than 95 percent, even in the long term does not deform under load, good mechanical strength to withstand more cables for longer floating away. 5, to avoid eddy: current flowing through the cable process will produce a magnetic field, the composite material with high insulation to avoid magnetic bracket form a closed loop to produce circulation. 6, high-strength lightweight, weighing only 1/4 of steel frame, concrete support about 1/10 of simple construction. Easy to transport; 7. fire retardant: heat, cold. Fire excellent performance, good fire-retardant properties, burning rate (a 25, smoke density is less than or equal to 500, the oxygen index of 29 or above, can be used in a range of -40 to 150 degrees Celsius, safe and reliable). 8, long life: 50 years underground, the ground for 25 years, long life, durable, safe and nontoxic, 9, environmental security: GRP Material Safety nontoxic, and no recycling value, solve the problem fundamentally is stolen . Fourth, Yu Cheng new FRP cable bracket data list: the new FRP cable bracket Spec stent type performance parameters Standard fire rating B1 level bending strength (MPa) ≥150 flexural modulus (MPa) ≥10 × 103 compressive strength (MPa) ≥70 Impact strength (kJ / m2) ≥55 Water absorption (%) <0.2 Heat distortion temperature (℃)> 200 Density (g / cm3) <2 fiber content ≥15% Insulation resistance ≥1.0 * 1012Ω new glass and steel cable bracket Traditional angle bracket Technical Specifications Contrast: Project power cable insulation bracket galvanized angle bracket density (g / cm3) 1.80 7.85 16 790 corrosion than strength (80 ° / 100h) 0.012 0.023 dielectric strength (kv / mm) 14.0 conductive flame retardant in line with FH-1 - Water resistance (%) 0.11 - corrosion resistant, acid and alkali salts corrode, rust insulation insulated conductive mechanical strength to the top 1.0cm top deflection force 2.5kN 2.5kN force deflection 1.2cm lateral force 0.5kN top horizontal offset horizontal offset 7cm 7cm top weight weight eddy current effects (loss) lossless great difficulty manufacturing process easy to process more long cycle cable sheath abrasion test show no visible damage a little Visible damage to the raw materials are cheap, abundant resources more expensive, some imported maintenance free maintenance 5--7 years once the required repairs ease the mounting process time is short, easy to install long time, difficult to install the service life of 30 to 10 years five, Yu Cheng new FRP Installation methods and precautions cable bracket installation steps: a bracket including fiberglass columns, supporting arm, pin (bolt) and polymer fixed cap installation tool as an ordinary electric drill, drill bits, wrenches. 1, column installation: positioning line the back post with mounting holes with a diameter Ф12.5, according to construction plans and post installation hole locations, using M12 expansion bolt fixed between the uprights on the wall, bolts and gaskets must be installed column , slotted wall uprights as snapping. 2, Cable: The cable drag cable bracket position. 3, the supporting arm installation: According to the supporting arm layer spacing requirements, positioned on both sides of the column lines have been reserved for a fitting hole, aperture Ф8.5; bolt the bracket arm fixed to the groove column, bolts properly tensioned bolts and columns Note must be installed between the pads. 4, cable and fixed in place: the cable placed in the bracket and lashing good, try the heaviest cable roots when placed on the supporting arm. Note: 1, the installation of the cable bracket close to the wall to prevent loosening. 2, other support than to stand on a scaffold or cable is strictly prohibited. 3, laying cable, the cable is prohibited falling from a height, it should be directly placed in the bracket. 4, laying and maintenance, to avoid pulling the cable in the bracket, effective measures should be adopted to avoid lateral supports force. Slow force 5 from the cable to be adjusted when the local, should be moved to bracket the root of the cable drag, or the need to adjust the cable between the supports hold up after construction to avoid overload.
