Description
Technical field
The present invention relates to field of cable technology, more particularly to a kind of communication power supply flame-proof power cable.
Background technology
Communication power supply is the critical infrastructures of whole communication network, but what communication power supply accounted in the whole communications industry
Ratio is simultaneously little.The mainly annual plant maintenance of buying of the telecom operators on power supply product and system equipment, wherein electricity
The proportion that the maintenance of source device generally accounts for amount of purchase is higher.The expense phase that telecom operators are used in the construction of power-supply system every year
To less, unless telecommunication system needs large-scale upgrading or enlarging, operator just to increase the amount of purchase of power-supply device.
Cable is typically by several or several groups of wires（Every group at least two）The cable for the similar rope being twisted, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.Cable has
Interior energization, the feature of external insulation.
Communication power supply with flexible cable be it is a kind of be used to moving, telecommunications, the equipment of the communication machine room such as Netcom are powered connecting line, production
Product require the performance such as soft, fire-retardant.Existing communication power supply with flexible cable when in use, easily by the shadow of external electromagnetic signal
Ring, cause equipment not work.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of communication power supply fire-retardant electric power electricity
Cable.
The present invention is to be achieved through the following technical solutions：
A kind of communication power supply flame-proof power cable, including the cable core and outer insulation jacket being made up of more copper wires, the electricity
Interior insulation set is provided with the outer surface of cable core, to be fixedly connected between the cable core and interior insulation set, the interior insulation
Set outside from being disposed with flame retarding material, housing, in addition to low smoke and zero halogen glass wool cloth band, low smoke, zero halogen from the inside to the outside
Polyolefin protective layer and refractory masses, steel wire armor layer, the steel wire armour are provided with the housing outer circumference direction
Shielding piece is provided with the outside of dress layer, is provided with screen layer on the outside of the steel wire armor layer, on the screen layer internal circumference direction
It is provided with several shielding projections.
As the preferred technical solution of the present invention, the steel wire armor layer uses aluminium wire or copper wire.
As the preferred technical solution of the present invention, the shielding piece is in W fonts.
As the preferred technical solution of the present invention, the material of the screen layer is fiber reinforced ceramic.
As the preferred technical solution of the present invention, the shielding curved convex of projection.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention shielding piece, can be with the presence of screen layer
The shielding of effective increase cable so that the cable has preferable shield effectiveness to outer signals when in use, it is ensured that sets
Standby normal work.
