Abstract
The invention relates to an aluminum core self-supporting power cable for communication, which comprises an aluminum conductor. A polyvinyl chloride insulating layer is formed outside the aluminum conductor, a formed insulated wire of the aluminum conductor is stranded with a steel wire covered with a polyethylene insulating layer, and a polyethylene outer sheath is arranged outside the stranded wire core. The power cable has a simple structure; the aluminum conductor is stranded with the steel wire to increase the tension and strength of the cable; meanwhile, the outer sheath adopts the same polyethylene outer sheath as an optical cable, so the requirements for ageing resistance against external environment and ultraviolet long-term irradiation resistance can be met; therefore, the far-end power supply for an optical cable unit is realized, and the service life of the cable is prolonged.
Description
Technical field
The present invention relates to a kind of power cable for communication, relate in particular to a kind of aluminum core self-supporting power cable for communication.
Background technology
Aluminum core self-supporting power cable for communication is in order to satisfy the requirement of optical cable unit far-end power supply; the power cable of joint using at optical cable; the electricity consumption of solution equipment; signal transmission issues; because present fiber-to-the-home transmission means; the place that far-end need be powered relatively disperses; can't set up machine room; the cold and hot temperature difference is big in the outdoor environment; the dustproof and rainproof measure is not in place; as adopting the storage battery power supply mode can't guarantee again to the protection of battery; and adopt storage battery power supply because storage battery must discharge and recharge for a long time, battery life generally within 2 years, causes a large amount of battery pollutions.If in the direct power taking of far-end, when outage, can't guarantee voice call, can't dial the flash appeal phone.
Summary of the invention
The present invention provides a kind of aluminum core self-supporting power cable for communication in order to overcome the above problems, satisfied needed tension force requirement when setting up, simultaneously oversheath adopts the polyethylene oversheath identical with optical cable, has satisfied that external environment is anti-aging, the requirement of UV resistant long-term irradiation.
Technical scheme of the present invention is: a kind of aluminum core self-supporting power cable for communication, include aluminium conductor, aluminium conductor is provided with the polyvinyl chloride insulation layer outward, and the aluminium conductor insulated wire cores of formation is stranded with the steel wire that is covered with polyethylene layer, is provided with the polyethylene oversheath in the stranded core outside.
Advantage of the present invention is: the present invention is simple in structure, stranded tension force and the intensity that has increased cable of aluminium conductor and steel wire, oversheath adopts the pe sheath identical with optical cable simultaneously, can satisfy that environment to external world is anti-aging, the requirement of UV resistant long-term irradiation, so just solve the far-end power supply of optical cable unit, also prolonged the useful life of cable.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is aluminium conductor among the figure, the 2nd, and polyvinyl chloride insulation layer, the 3rd, steel wire, the 4th, polyethylene layer, the 5th, polyethylene oversheath.
Embodiment
A kind of aluminum core self-supporting power cable for communication includes aluminium conductor 1, the aluminium conductor 1 outer polyvinyl chloride insulation layer 2 that is provided with, and aluminium conductor 1 insulated wire of formation is stranded with the steel wire 3 that is covered with polyethylene layer 4, and the core outside after stranded is provided with polyethylene oversheath 5.
The present invention has increased the tension force and the intensity of cable, satisfied that environment to external world is anti-aging, the requirement of UV resistant long-term irradiation, useful life is longer, be applicable to the power cable of joint using with optical cable, be the power supply of optical cable unit far-end, the electricity consumption of solution equipment, signal transmission issues are worth promoting.
