High temperature cable is divided into: organic polymer material high temperature cable and inorganic material ultra high temperature cable.
1. The high temperature cables of organic polymer materials are mainly fluoroplastics and silicone rubber cables.
01 Fluoroplastic insulated wire and cable
Fluoroplastics are an important category of plastics. Usually people know fluoroplastics from contact with the king of plastics - polytetrafluoroethylene (PTFE). In fact, polytetrafluoroethylene is only the fluoroplastic with the largest output and consumption. The commonly used fluoroplastics for wires and cables are: polyperfluoroethylene propylene (FEP, commonly known as F46), polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene copolymer (ETFE, commonly known as F40), polyvinylidene fluoride (PVDF), etc.
Fluoroplastic cables mainly include: high temperature communication cables, high temperature resistant lead wires and installation wires, high temperature compensation wires and high temperature resistant power and control signal cables for industrial use, radiation resistant cables for atomic reactors and wires for rolling stock, etc.
02 Silicone rubber insulated wire and cable
Silicone rubber is mainly a polymer material formed of silicon element instead of carbon element. Silicone rubber has good heat resistance. The commonly used silicone rubber for wires and cables is methyl ethylene silicone rubber, and the working temperature range is -60 ° C ~ 180 ° C.
2. Inorganic material ultra-high temperature cable
It is poor in nature, and its insulation performance is lower than that of polymer materials, but its excellent high temperature performance can meet the needs of special high temperature industries.
01 Mineral insulated fireproof cable
The product structure is copper core copper sheathed magnesium oxide insulated cables, mainly power cables, control cables, heating cables and cloth wires. The normal working temperature is 250℃, but the actual working temperature can be higher, because the melting point of magnesium oxide is 2852℃, which is much higher than the melting point of copper (1083℃), and the cable can be reused safely after fire.
The production process of mineral insulated fireproof cable is as follows:
The mineral insulated fireproof cable produced by Fengming Cable Factory has high temperature resistance, fire resistance, explosion-proof, waterproof, radiation resistance, strong corrosion resistance, high mechanical strength, good grounding performance, small size, long life, large current carrying capacity and overload capacity. strong characteristics.
02 Inorganic package insulated ultra-high temperature cable
The inorganic insulating wrapping insulated cables produced by Fengming Cable Factory are generally made of inorganic wrapping tapes and wires, and the cables are processed by technology. As a high temperature resistant material, refractory tape can still maintain normal insulation performance at 800 °C, so it is one of the main materials for high temperature resistant cables; The temperature is above 600 ℃, and it is processed by weaving process, which is also used as a reinforcement; the above two materials cannot form tightness and tight insulation, so the insulator can be formed by coating inorganic curing paint, silicon powder and borax.
