Plastic cables are wires and cables with rubber padding and sheath.
According towards purpose, there are electrical power cables, control and sign cables, marine cables, aviation converter cables, mining cables, and set up wires.
The insulating layer and sheath are made of natural rubber, styrene-butadiene plastic, ethylene-propylene rubber, etc. In addition to satisfying the insulation effectiveness and physical and mechanical properties, they require growing old resistance and abrasion opposition. Some products require oil resistance and flame retardancy.
Wires and cables are usually extruded and continuously vulcanized. Products utilized in all walks associated with life.
The full title of Ethylene Propylene Rubber (EPR) is cross-linked ethylene-propylene plastic. It has the balance of oxygen resistance, ozone weight and partial discharge stableness. It also has fantastic cold resistance characteristics, perhaps at -50 ℃, the item still maintains good Mobility.
In addition, it includes excellent weathering resistance as well as light stability. In specific, it is halogen-free as well as has flame-retardant properties. The ethylene-propylene rubber insulated wire with chlorosulfonated polyethylene sheath would work for places that necessitate flame-retardant. Ethylene-propylene rubber insulated cables have not been widely used throughout my country, but they've got been widely used to foreign countries, especially in Europe. It has excellent electrical and hardware properties, and has beneficial high temperature resistance sometimes in humid environments. The long-term allowable working temperature belonging to the core can reach 90℃, and also the allowable temperature of short-circuit thermal stability is 250℃.
A technique for preparing radiation-resistant, low-smoke, halogen-free, flame-retardant ethylene-propylene rubberized cable material, by adding ethylene-propylene rubber, aluminum hydroxide, silicone flame-retardant synergist, head compound, anti-aging agent, as well as anti-copper into an inner mixer After heating along with mixing, γ-ray absorber, liquid peroxide vulcanizing agent and phenolic heat stabilizer are air-cooled by way of a twin-screw extruder.
Ethylene-propylene rubber has a large dielectric loss issue, so it is only found in power cable lines with a voltage level of under 138kV. Due to favorable water resistance of ethylene-propylene rubberized, ethylene-propylene rubber cables are worthy of submarine cables, and simply because ethylene-propylene rubber has great soft characteristics, it is more ideal for laying in mines and ships.
