FRP кабельных лотков

Pultruded FRP cable tray is manufactured by a kind of high temperature continuous technics formed product, it composed with dipped woven glassfiber, fire resistance surface mat and other continue strengthen material, and pass by the cable tray mould, then finish after cured. FRP pultruded cable tray, have characteristics as light weight, fire, corrosion and heat resistant, and high mechanical strength etc. If customer request shielding effectiveness cable tray, we can make the alloy steel or copper screen compose with pultrusion to strengthen the anti-interference ability. Compared with same size steel cable tray, load ability are close, but the weight of FRP is very light only 1/4 of steel cable tray, corrosion resistance and service life will be decuple of steel cable tray. The fire resistance FRP cable tray is a new product developed base on steel cable tray, it has high strength, good insulation chemistry and fire resistance. So it widely used in petroleum, chemical industry, textile, light industry, metallurgy, mechanism, electric power, communication, underground carbarn and indoor or outdoor like national defense project and so on enterprise. The cable tray is applicable to voltage under 10kv power cable, control cable, lighting wiring, pneumatic and hydraulic cable. 1Oxygen index--------------------Oi≥43% 2 Compressive strength----------≥400kg/cm² 3 Tensile strength-----------------≥1250kg/cm² 4 Flexural strength----------------≥1370kg/cm² 5 Density----------------------------2100-2200kg/m³ 6 Flame retardancy: withstand 800°C flame for 15 minutes. 7 Load ability of cable tray: uniform load 80 kg/m, concentrated load 180 kg/m. 8 Smooth surface, flat and no cracks. 9 Circumstance temperature: -40 80°C 10 Earthing: having angle steel inside the cable tray, trace connect between each piece.
