The invention discloses a low smoke zero halogen fire-resistant soft cable. The low smoke zero halogen fire-resistant soft cable sequentially comprises a sheath layer, an insulation layer, a mica tapelayer and conductors from outside to inside, wherein the material of the sheath layer is an environmental-friendly low smoke zero halogen polyolefin material resistant to a high temperature of 110 DEG C, the material of the insulation layer is a cross-linked polyethylene insulation material resistant to a high temperature of 110 DEG C, the mica tape layer is formed by winding dual layers of calcined gold mica tapes in a lamination and overlap joint way, each conductor is formed by twisting a plurality of annealing naked copper wires, the fire-resistant temperature of the cable reaches 1,050 DEG C and is infinitely approximate to a melting point of copper, the cable still can effectively develop an effect even the temperature of large fire exceeds 950 DEG C but is lower than the melting point of copper, the application safety is greatly improved, and the life safety of a person is guaranteed.
