Abstract

The utility model relates to an optical fiber composite medium-voltage insulated cable, wherein an optical unit (2) is a nonmetal layer stranded optical fiber cable or a nonmetal central tube optical fiber cable, and electric units (1) are 10-1600-square-millimeter copper conductor cables with a metal shield (13) on insulating wire cores. The optical unit (2), the electric units (1) and necessary filling ropes (3) are twisted into a cable core, of which the outside is coated with a tape (4), an inner lining layer (5), an armor layer (6), an outer sheath (7) and tearing ropes (8) in sequence, which provides convenience for composite cable stripping in construction.

Description

Press insulated cable in the Optical Fiber Composite

Technical field

The utility model relates in a kind of Optical Fiber Composite presses insulated cable; Comprise light unit, electric unit, the stranded stranding of gasket for packing; The cable core outside coats covering, inner covering, armour, oversheath successively; In the 6/30kV transmission line, have optical fiber communication function and electric power transfer function concurrently, belong to the compound cable of photoelectricity field.

Background technology

Along with State Grid Corporation of China strengthens the construction to intelligent grid; Except backbone network is built high pressure, superhigh pressure, large capacity transmission circuit energetically; And try hard to recommend at user side that Fiber to the home (PFTTH); Arrive intelligent grid engineerings such as family through implementing power optical fiber, electrical network and telecommunications network, broadcasting and television network, the Internet etc. will be organically blended.And the construction of intelligent grid must use optoelectronic composite cable as support, presses in the intelligent grid process of construction of city at present in the Optical Fiber Composite that a kind of light harvesting signal and middle piezoelectric signal be transmitted in one and presses insulated cable.

Summary of the invention

Press insulated cable in the Optical Fiber Composite that the purpose of the utility model is to provide a kind of light harvesting signal and middle piezoelectric signal to be transmitted in one.

The technical scheme that the utility model adopts is: press insulated cable in a kind of Optical Fiber Composite, wherein the light unit is non-metallic layer stranded cables or nonmetal central beam tube type optical cable, and electric unit is the 10-1600mm that has metallic shield on the three insulated cores ²The copper conductor cable, light unit and electric unit and necessary gasket for packing are twisted into cable core, and the cable core outside once coats band, inner covering, armour, oversheath.

The utility model has the advantages that:

1, the utility model photoelectricity one, realization photoelectricity is constructed simultaneously, and the construction period is short, reduces operating expenses.

2, the light unit of the utility model employing is non-metallic layer stranded cables or nonmetal central beam tube type optical cable, and this optic cable diameter is little, and available fiber number is many, can communicate optical signal be provided for a plurality of users.

3, the electric unit of the utility model employing is the copper conductor cable of tape insulation layer, has also played the effect of protection light unit and copper conductor when the signal of telecommunication is provided.

4, the utility model adopts gasket for packing, has guaranteed the structure of cable core, has practiced thrift cost.
