Abstract

The invention discloses an oil tank-used series-type constant power electric tracing band, which comprises a heating part. The heating part is formed by parallelly-arranged three groups of heating units. Each heating unit group is formed by a heating core and an insulated layer coating the heating core. The heating part is coated with a sheath layer, the sheath layer is coated with a metal braiding layer, the metal braiding layer is coated with a reinforced layer, and the reinforced layer is made of polypropylene material. The oil tank-used series-type constant power electric tracing band has good anti-corrosion and anti-aging performance.

Description

Technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a series-type constant power electric heating cable for oil tanks. Background technique [0002] The tandem electric heating cable is a special cable that generates heat after being heated by electric energy. It has been widely used in petroleum, chemical, pharmaceutical and food industries for heat preservation, antifreeze and constant temperature control. The principle is that when the core wire passes a large current, it generates Joule heat by itself, thereby achieving the effect of generating electric heating. In the field of oil tanks, the working environment of oil tanks is harsh, and there are high requirements for the corrosion resistance and aging resistance of electric heating cables. The existing electric heating cables are difficult to apply. How to prepare a series constant power electric heating cable for oil tanks with good corrosion resistance and agin...
