Since all the materials used in this kind of insulated cables are inorganic materials, such as: nickel plated copper wires, pfa insulated wires, silicone high voltage wire, so they all have some advantages that other cables may not have.
1,Fire-resistant: The two materials used in insulated cables, copper and mineral insulation, are inorganic. This kind of cable will not burn, will not help to ignite, in close to the conditions of the flame can still continue to operate. The copper sheath melts at 1083℃.
2, high operating temperature: insulated cable can withstand continuous operating temperature up to 250 ℃. And, in case of emergency, the cable can continue to operate at temperatures close to the melting point of the sheath for a short period of time.
3, long life: inorganic materials applied in the insulated cable, can ensure that the cable has stability, long life and fire resistance.
4, explosion-proof: insulated cables in a high degree of compaction of the insulating material, can prevent vapours, gases and flames in the cable connected to the equipment parts through.
5,Small outer diameter: The diameter of insulated cables is smaller than other cables with the same current rating.
6, waterproof: If the insulated cable is completely submerged in water, with the help of its seamless metal sheath, the insulated cable can continue to operate.
7, high mechanical strength: insulated cables are robust and can withstand severe mechanical damage without impairing their electrical properties.
8, high current-carrying capacity: for the same cross-section of the cable, insulated cables than other types of cables to transmit a higher current. At the same time, insulated cables can also withstand considerable overload.
9, short-circuit fault rating: at the same temperature, the short-circuit fault rating of insulated cables is significantly higher than other types of cables.
10, grounding: for insulated cables, a separate grounding conductor is not required, because the copper sheath used for this cable already serves as a grounding conductor, providing a good low grounding resistance. In the case of grounded sheath circuit (ESR) cabling, the outer copper sheath can be used as the ground and neutral conductor in MEN (Multi Earth Neutral) systems.
11, high corrosion resistance: the copper sheath of the insulated cable has high corrosion resistance, for most installations, it does not need to take additional protective measures. In the copper sheath of the cable is susceptible to chemical corrosion or industrial staining of serious places, should be used to protect the insulated cable wrapped in plastic outer sheath.
