Abstract
The utility model relates to a special type environmental-friendly medium voltage cable with the termite-proof, rat- proof and waterproof nylon sheath. An internal shielding, a cross-linked polyethylene insulating layer and an external shielding are wrapped on water blocking conductor in three-layer joint wrapping mode. A water blocking tape is wrapped on the external shielding, a concentric copper wire shielding is wrapped on the water blocking tape, finally a polyethylene inner sheath, a nylon middle sheath and a polyvinyl chloride outer sheath are wrapped on copper wire shielding in sequence. The utility model is large termite-proof, rat-proof, anti-rrosion, abrasion-proof etc, thereby greatly increasing the waterproof performance, electrical performance and service life of cable greatly.
Description
Affiliated technical field
The utility model relates to the extraordinary midium voltage cable of the termite-proof anti-rat eaten waterproof nylon sheath of a kind of environment-friendly type, belongs to technical field of electric wires and cables.
Background technology
Bury the ground power cable for the field, be subjected to gnawing of rodents such as termite, mouse through regular meeting; At the coastal south, environment is relatively moist and with salt fog, and the aging aggravation of cable material causes cable seriously to shorten useful life.At present, the termite-proof anti-rat eaten of medicine is adopted with power cable in the field with burying usually.Through facts have proved, this method is relatively more effective in the early stage, but as time passes, the medicine in the cable material can produce volatilization, reduces the ability of the termite-proof anti-rat eaten of cable; Simultaneously, the medicine in the cable material can pollute environment and soil, also can discharge pernicious gas when cable is produced, and works the mischief to the workman is healthy; The common cable anti-corrosion capability is poor in addition, also causes cable shortening in useful life.
Summary of the invention
The purpose of this utility model provides the extraordinary midium voltage cable of a kind of good electric property, termite-proof anti-rat eaten, waterproof, anticorrosion, wear-resisting and long service life.
The technical solution of the utility model is: it is made up of conductor, inner shield, insulating barrier, external shield, waterstop, copper wire shielding, inner sheath, middle sheath, oversheath.Extrude inner shield, insulating barrier and external shield in three-layer co-extruded mode on the aluminium conductor that blocks water, the wrapped one deck waterstop of order, copper wire shielding with one heart successively extrudes the polyethylene inner sheath, sheath and polyvinyl chloride oversheath in the nylon again in external shield.
The beneficial effects of the utility model are: by use block water aluminium conductor and wrapped waterstop and polyethylene inner sheath, can realize vertically and waterproof simultaneously radially, improved water resistance greatly, because nylon sheath wire has excellent mechanical performance, and have characteristics such as heat resistance, oil resistant, wear-resisting, hardness height.Thereby, can realize termite-proof anti-rat eaten, anticorrosion and wear-resisting effect by extruding nylon sheath wire.The electric property and the useful life of this cable have so just fundamentally been improved.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.

Embodiment
As shown in the figure: the extraordinary midium voltage cable of the termite-proof anti-rat eaten waterproof nylon sheath of a kind of environment-friendly type.It is to extrude inner shield 2, crosslinked polyetylene insulated layer 3 and external shield 4 in three-layer co-extruded mode on the aluminium conductor 1 that blocks water.Wrapped one deck waterstop 5 in external shield 4.Wrapped concentric copper wire shielding 6 on waterstop.In copper wire shielding 6, extrude sheath 8 and polyvinyl chloride oversheath 9 in polyethylene inner sheath 7, the nylon at last successively in proper order.
Claims (1)
- The extraordinary midium voltage cable of the termite-proof anti-rat eaten waterproof nylon sheath of a kind of environment-friendly type, it is characterized in that: on the aluminium conductor that blocks water, extrude inner shield, crosslinked polyetylene insulated layer and external shield in three-layer co-extruded mode, wrapped one deck waterstop in external shield, wrapped concentric copper wire shielding on waterstop extrudes sheath and polyvinyl chloride oversheath in polyethylene inner sheath, the nylon more successively in proper order in the copper wire shielding.
