Abstract
The utility model discloses a skin-effect heat tracing cable, which comprises a nickel-plated copper-braided bus, wherein a fluoropolymer-containing insulation layer is formed outside the nickel-plated copper-braided bus by extrusion; a fluoropolymer-containing wearproof sheath is formed outside the insulation layer by extrusion; and a heat pipe is sleeved on the wearproof sheath. The heat tracing cable is reasonable in structural design, and the insulation layer and the sheath layer are made of a fluoropolymer material, so that the insulating property and the wearproof property of the cable are improved; and moreover, by the design of the heat pipe and a heat preservation layer, a heat tracing effect of the cable is excellent.
Description
Technical field:
The utility model relates to the accompanying-heat cable technical field, relates in particular to a kind of kelvin effect accompanying-heat cable.
Background technology:
The accompanying-heat cable that kelvin effect is used is applicable to irrigated area, technique unit mostly and the heating of the long distance line between the facility of removing stage makeup and costume is used, because it has flexibility, can be used for holding temperature, antifreeze and heating, also be widely used in the industries such as oil, chemical industry, electric power, natural gas, iron and steel, oil refining, petrochemical industry, paper pulp/papermaking, mining.
Compare the conventional resistance-type accompanying-heat cable that is used for long-distance transport pipes, the accompanying-heat cable of kelvin effect does not need a large amount of distribution facilities, be a very economical scheme, can accompany heat to more than ten kilometers pipeline from a power supply point, be specially adapted to deep-well companion heat or remote except freezing.
The utility model content:
In order to remedy the deficiencies in the prior art, the purpose of this utility model provides a kind of kelvin effect accompanying-heat cable, reasonable in design, and holding temperature, antifreeze and heating are effective, practical easily.
The technical solution of the utility model is as follows:
The kelvin effect accompanying-heat cable, it is characterized in that: comprise nickel plating braiding copper wire bus, the outer extrusion moulding of nickel plating braiding copper wire bus has the insulating barrier of fluoropolymer, and the outer extrusion moulding of insulating barrier has the anti-wear sheath of fluoropolymer, and anti-wear sheath is set with heat pipe outward.
Described kelvin effect accompanying-heat cable is characterized in that: also be provided with heat-insulation layer between described heat pipe and the anti-wear sheath.
Described kelvin effect accompanying-heat cable is characterized in that: the sectional area of described nickel plating braiding copper wire bus is generally 24～36mm.
The utility model has the advantages that:
The utility model reasonable in design, insulating barrier and restrictive coating adopt fluorinated polymer material, have improved insulation property and the anti-wear property of cable, and the simultaneously design of heat pipe and heat-insulation layer is so that companion's thermal effect of cable is superior.
