The utility model relates to a fire-proof intermediate cable, which adopts an anti-static intermediate cable sheath material as a sheath layer, and is also provided with a fire-resistant master tape layer, and the fire-resistant master tape layer is arranged between the sheath layer and the cable conductor. The anti-static intermediate cable sheath material contains resin powder with a degree of polymerization of 1000-1300, dinonyl terephthalate, chlorinated paraffin, polyethylene oxide, flame retardant, nano-calcium carbonate, stabilizer, anti- Static agent A, antistatic agent B, stearic acid and polyethylene wax. The invention adopts the synergistic effect of antistatic agent A, antistatic agent B and flame retardant, wherein the product material itself is modified according to the antistatic requirement, the resistivity of the material is reduced, the antistatic effect is improved, and the fire protection is better. Anti-static effect. |
