Abstract

The invention discloses an anti-corrosion and anti-explosion self-temperature-control electric tracing band. The anti-corrosion and anti-explosion self-temperature-control electric tracing band comprises a PTC material core which is internally provided with two wires, the PTC material core is wrapped by a single-face metal and plastic composite belt which is internally provided with a drainage wire, the plastic layer of the single-face metal and plastic composite belt faces inwards, and the metal layer of the single-face metal and plastic composite belt faces outwards. The metal and plastic composite belt is wrapped by an insulating layer, the insulating layer is wrapped by a braided shield layer, the braided shield layer is wrapped by a restrictive coating, and the periphery of the restrictive coating is provided with a plicated texture. The anti-corrosion and anti-explosion self-temperature-control electric tracing band is simple in structure and good in electromagnetic shielding performance and can be used safely under the high-temperature environment.

Description

technical field

[0001] The invention relates to the technical field of electric heating cables, in particular to an anti-corrosion and explosion-proof self-temperature-controlling electric heating cable. Background technique

[0002] Anti-corrosion and explosion-proof self-control temperature electric heating cable has become the most common type of electric heating cable in the world today. They can be widely used in the transportation of liquid objects in pipelines, antifreeze and heat preservation of tanks, maintenance of process temperature, heating of roads, ramps, crosswalks, eaves and floors, etc. Inside the anti-corrosion and explosion-proof self-controlling electric heating cable, a positive temperature coefficient (PTC) material for heating is distributed between two conductive cores, and its exterior is composed of a polymer inner sheath, a metal shielding net and a polymer outer sheath. When the power is turned on, the internal PTC material expands when heated, ...

Embodiment Construction

[0016] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of an anti-corrosion and explosion-proof self-control temperature electric heating cable proposed by the present invention.

[0017] refer to figure 1 , an anti-corrosion and explosion-proof self-control temperature electric heating cable proposed by the present invention, which includes a PTC material core 2 inside.

[0018] The PTC material core 2 is made of carbon-added conductive plastic, and two wires 1 are arranged inside the PTC material core 2, and each wire is formed by twisting 7 tinned copper wires. The PTC material core 2 is made of carbon-added conductive plastic.

[0019] The PTC material core 2 is coated with a single-sided aluminum-plastic composite layer 3, the plastic layer of the single-sided aluminum-plastic composite layer 3 faces inward, and the aluminum layer faces outward, which acts as a protective layer for the core body, which can prevent moisture and external chemical...
