A cable for heating

Abstract

The application relates to the technical field of automobile heating elements, in particular to a cable for heating, which comprises a conductor, an insulating layer and an outer covering, the insulating layer is sleeved on the conductor, and the outer covering is sleeved on the insulating layer; the conductor is a copper-nickel alloy, the resistance value of the copper-nickel alloy is 1.5 ohms / m, and the insulating layer is polyimide paint; the copper-nickel alloy conductor with the resistance value of 1.5 ohms / m is adopted, compared with the tin-copper alloy conductor with the resistance value of 1 ohm / m in the prior art, the heating efficiency is improved under the same current condition, the problem that the automobile cushion heating cable is slow to heat up in a low-temperature environment is effectively solved, the heating demand of a user for a seat can be quickly met, and the comfort experience is improved; meanwhile, the conductor is composed of multiple copper-nickel alloy wires and is plated with nickel on the surface, the structural stability and the conductivity of the conductor are enhanced, the polyimide paint insulating layer is tightly wrapped, the heating is ensured to be uniform and stable, local overheating is avoided, and the heating performance is further optimized.
