Abstract

The utility model relates to the field of household communication electrical equipment, and particularly to an integrated cable. The three-core integrated cable for the aviation electric appliance comprises a power cable core, an optical fiber communication cable core and a data cable core. An insulating layer is wound outside the power cable core for forming a power core wire. After an insulating layer is wound outside the data cable core, the data cable core and a grounding wire are wound by an aluminum foil for forming a data core wire. One data core wire, one optical fiber communication cable core and one power core wire are arranged in a regular triangle shape for intertwisting to a cable. Then an inner sheath, a shielding armoring layer and an outer sheath are successively wound from inside to outside. The outer sheath is made of vulcanized styrene-butadiene rubber. The clearance among the core wires is filled by filter. According to the integrated cable, the optical fiber communication cable core, the power cable core and the data cable core are integrated in one cable, and are rounded by filler. Excellent fireproof performance of the cable is obtained while excellent electric performance is ensured. The integrated cable can be used in harsh outside environment.

Description

Air appliance is with three core composite cables

Technical field

The utility model relates to family expenses communication electric power equipment field, relates in particular to a kind of composite cable.

Background technology

Increasing along with people's demand to information in productive life, more and more widely, mechanics of communication is advanced by leaps and bounds, and presents information technology prosperity scene in the ascendant.Extensively adopt in each field under the demand of information technology, should need and the communication product of giving birth to is broken through the soil one after another like rain the back spring bamboo.Yet, on the great equipments such as the Aero-Space high in big, the fire-retardant requirement of high low temperature difference variation, that communicating requirement is strict, naval vessel, offshore platform, oil exploration, power plant, little because of the communication products demand, quality requirement is strict, performance constantly changes requirement because occasion is different, so far aspect high-end communication products especially communications cable product aspect also form industry standard and the product line of specialty.

Generally adopt electric power and the separate cable system of data on the existing air equipment.There are problems such as cable laying cost height, degree-of-difficulty factor are big usually in this type of cable, owing to need to lay the multiple tracks cable, has wasted the space in addition, and this influence for the less air equipment of volume is bigger.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of air appliance with three core composite cables, this cable is integrated into optical-fibre communications cable core, electric power cable core and data cable core three in the cable, and use the filler rounding, when having excellent electric property, make cable have excellent fireproof performance, can under abominable external environment condition, use.

The utility model is achieved in that a kind of air appliance with three core composite cables, comprises electric power cable core, optical-fibre communications cable core and data cable core; The outer lapped insulation layer of described electric power cable core becomes the electric power heart yearn, behind the outer lapped insulation layer of described data cable core with earth connection by the wrapped data heart yearn that becomes of aluminium foil; One single data heart yearn, an optical-fibre communications cable core become equilateral triangle to arrange stranded stranding with an electric power heart yearn, from inside to outside wrapped inner sheath, shield layer and oversheath in turn then, described oversheath is sulfuration butadiene-styrene rubber, and the gap between the described heart yearn is filled by filler.

Described optical-fibre communications cable core comprises optical fiber, the filling of optical fiber cream, loose sleeve pipe, aramid yarn and protecting pipe, the stranded back of optical fiber outsourcing pine sleeve pipe, and the space in the loose sleeve pipe is filled by optical fiber cream, and loose sleeve pipe outsourcing aramid line extrudes protecting pipe again.

Described inner sheath is flame retardant rubber.

Described shield layer is the zinc-coated wire braid.

Described electric power cable core and data cable core are stranded silver-gilt copper wire conductor.

Described insulating barrier is the PET nonwoven fabrics.

Described filler is polypropylene flame redardant.

The utility model air appliance is integrated into optical-fibre communications cable core, electric power cable core and data cable core three in the cable with three core composite cables, and uses the filler rounding, makes cable have excellent fireproof performance when having excellent electric property; This cable signal transmission frequency height, shield effectiveness is good, and anti-electromagnetic interference capability is strong, and tensile strength and voltage withstand class height can use under abominable external environment condition.
