Abstract
The utility model discloses a fireproof insulation radio frequency cable which comprises conductors, a fire proof winding layer, a steel band armored layer, and a polyethylene over-sheath. The conductor is wrapped tightly in a successive manner from outside to inside by a flame retardation mica tape, a composite aluminum-plastics tape winding and shield layer and a natural butadiene styrene rubber insulation layer. The conductors are arranged in such a manner that two groups of three twisted wire cores form the two cable cores. The composite aluminum-plastics tape winding and shield layer is provided with four ground wire cores. The gap between the natural butadiene styrene rubber insulation layer and the conductors is filled with flame retardant. The outer part of the flame retardation mica tape is tightly wrapped by the polyethylene over-sheath and the steel band armored layer. The utility model is simple in design, stable in performance, and can satisfy the function requirements of radio frequency electric cables. Beyond that, the electric cable is flexible which enables it to be easily arranged. Electric current can circulate through the cable in a rather stable manner. It is also wear resisting and stretch proof.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fire-proof insulation radio frequency cable.
Background technology
At present, along with developing rapidly of science and technology, cable industry also becomes Chinese second largest industry, simultaneously, China is also the first electric wire producing country in the world, due to the increase of cable demand, thereby require the variation of cable feature, radio frequency cable is the cable of electromagnetic energy in transmission radio-frequency region, also be indispensable element in wireless communication system and electronic equipment, and in different environments for use, just require cable to there is different functions, a lot of cable features are on the market more single, can not adapt to these more special environment, thereby grow with each passing day to the demand of radio frequency cable in market, the cable of various satisfied different demands need to be provided.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of fire-proof insulation radio frequency cable.
Scheme of the present utility model is as follows: a kind of fire-proof insulation radio frequency cable, it is made up of conductor, fire-resistant lapping layer, steel-tape armouring layer and outer protective polyethylene cover, and described conductor ecto-entad is to be extruded and formed by fire-resistant isinglass belt, aluminium-plastic tape lapped shielding layer and natural butadiene-styrene rubber insulating barrier; Described conductor be by two groups of three cores respectively stranded forming form cable core; In described aluminium-plastic tape lapped shielding layer, be provided with four ground wire cores; The gap portion of described natural butadiene-styrene rubber insulating barrier and conductor is filled with flame retardant; Described fire-resistant isinglass belt is outward closely to be extruded and form by outer protective polyethylene cover and steel-tape armouring layer; Described core is tinned copper wire; The material of described flame retardant is glass fibre.
The beneficial effects of the utility model in sum: the utility model simplicity of design, stable performance, can meet the performance requirement of radio frequency cable, and cable softness is easy to lay, and has current stabilization, wear-resistant, the advantages such as stretch-proof.
