Abstract
The utility model discloses a high temperature constant power electric heating belt comprising two buses which are respectively coated with a high temperature composite insulation layer which is wrapped by an electric heating wire, high temperature resistant fireproof glass fiber and two layers of PFA sheaths. A copper wire braid layer is arranged between the two layers of PFA sheaths. The high temperature constant power electric heating belt has the advantages of good insulation performance, high temperature resistance and waterproofness and is suitable for asphalt and heavy viscous oil pipeline heat tracing. In addition, the braid layer adopts copper wire braiding, the overall strength of the electric heating belt is raised, and the electric heating belt can be used as a safe grounding line.
Description
Technical field
The utility model relates to a kind of ribbon heater product with permanent power, mainly is a kind of high-temperature constant-power ribbon heater.
Background technology
The caloric value of permanent power electrothermal belt unit length is constant, and the ribbon heater of use is longer, and the power of output is just larger, can shear arbitrarily according to the volume length of actual needs when using at the scene, and have flexibility, can easily be close to pipe surface and lay.And the high-temperature constant-power ribbon heater not only requires good insulation preformance, and high temperature resistant again waterproof, is applicable to pitch, heavy viscous oil pipeline companion heat.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-temperature constant-power ribbon heater, and it is good insulation preformance not only, and high temperature resistant again waterproof, is applicable to pitch, heavy viscous oil pipeline companion heat; Its braid adopts proof copper-wire braided in addition, has improved the bulk strength of ribbon heater, can be as protective earth.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of high-temperature constant-power ribbon heater, include two buses, it is characterized in that: described two buses are coated with respectively the high temperature composite insulation layer outward, described high temperature composite insulation layer is coated with heating wire, fire resistant glass fibre and two-layer PFA sheath outward successively, between the described two-layer PFA sheath proof copper-wire braided layer is arranged.
The high-temperature resistant of described high temperature composite insulation layer is 260 ℃.
Insulating material adopts resistant to elevated temperatures waterproof glass fiber and resistant to elevated temperatures PFA fluoroplastics in the utility model, so that the fluid holding temperature can reach 180 ℃ to 205 ℃.
Advantage of the present utility model:
The utility model is good insulation preformance only, and high temperature resistant again waterproof, is applicable to pitch, heavy viscous oil pipeline companion heat; Its braid adopts proof copper-wire braided in addition, has improved the bulk strength of ribbon heater, can be as protective earth.
