Cable heating device

Abstract

The invention relates to a cable heating device, which comprises a main insulation layer. The section of the main insulation layer has an elliptic structure; the main insulation layer is internally provided with three cable cores; the cable cores are arranged horizontally; each cable core is internally provided with a bus insulation layer and a bus; the bus is coated by the bus insulation layer; the bus is a copper wire or an aluminum wire; the main insulation layer is coated with a heating wire layer; the heating wire layer is internally provided with a heating wire; the heating wire layer is coated with an outer sheath layer; the outer sheath layer is coated with an insulation braiding layer; and the insulation braiding layer is coated with a reinforced sheath. The structure is reasonable; the manufacturing process and the technological process are advanced; requirements specified by a related standard can be met; user demands are met; a material with little thermal resistance and excellent electrical performance and mechanical performance is selected as insulation, the normal insulation resistance is no smaller than 50 Momega.Km, and by adopting the metal wire braiding shielding layer, the best shielding effects can be achieved.

Description

Technical field [0001] The invention belongs to the field of cable preparation, and specifically relates to a cable heating device. Background technique [0002] The development and application of special wire and cable with the advantages of environmental protection and energy saving has become one of the main development directions of my country's wire and cable industry during the "Eleventh Five-Year Plan" period. At the same time, in terms of national policy orientation, in 2009 the State Council announced the "Plan for the Adjustment and Revitalization of the Equipment Manufacturing Industry" and the "Outline of Qingdao's Medium- and Long-term Scientific and Technological Development Plan" promulgated by the Qingdao Municipal Government. Energy-saving products, especially after non-renewable resources are listed as national strategic resources, renewable resources such as wind power, hydropower, and nuclear power will be further developed. In this context, the emergence of ...
