Single-core nichrome stranded wire silicon rubber insulation electric heat tape

The utility model relates to a single-core nichrome stranded wire silicon rubber insulation electric heat tape that is mainly used for thermal insulation and heating of pipelines and containers of petrochemical industry, fire fighting, steel, power and the like. The electric heat tape is compounded sequentially from the six layers of a core wire (1), a first insulating layer (2), a second insulating layer (3), an inner protective sheath (4), a shielding layer (5) and an out protective sheath (6) from inside to outside. The core wire (1) is a single-core nichrome stranded wire, and the material of the first insulating layer (2), the second insulating layer (3), the inner protective sheath (4) and the outer protective sheath (6) is silicon rubber. In installation, the electric heat tape can be repeatedly bent, thus greatly prolonging the service life.
