Abstract
The utility model provides a water-resisting insulated overhead lead structure. The section structure of the insulated overhead lead comprises a strength core, a conductor layer, a conductor shielding layer and an insulating layer. Lapping layers are vertically lapped between each layer of the inductor layers. The effect of the utility model is that the water accumulation phenomenon in the low place of the existing insulation inductor is put right by the water-resisting insulated overhead lead structure, and therefore the problem of the oxidation corrosion of the insulated overhead lead is avoided. The structure reduces the maintenance cost of the circuit, and prolongs service life of the insulated overhead lead. The water-resisting insulated overhead lead structure is suitable for the insulated overhead conductors with rated voltage of 1kV, 10kV and 35kV, and as well as suitable for the insulated overhead lead without a strength core.
Description
Technical field
The utility model relates to a kind of structure of insulated conductor, particularly a kind of suspended insulated guide wire structure that blocks water.
Background technology
Suspended insulated guide wire since itself have in light weight, lay and many advantages such as easy to maintenance and cost is low, use so in the overhead transmission line of urban distribution network and rural power grids, have comparatively widely.Along with continuous advancement in technology, the appearance of the suspended insulated guide wire of band steel core strengthening core, more a new height has been brought up in the application of suspended insulated guide wire.
Because the particularity of suspended insulated guide wire use occasion, cause from the infiltration of the joint moisture of annex, the long-term suspended insulated guide wire that uses will form moisture accumulation at the low ebb place of insulated conductor, conductor is formed oxide etch, have a strong impact on the useful life of product, thereby influence the normal operation of transmission line, increased the maintenance cost of circuit.
Summary of the invention
The utility model provides a kind of suspended insulated guide wire structure that blocks water with regard to above problem, is beneficial to improve the good block-water performance of suspended insulated guide wire, can prevent the infiltration of moisture effectively, avoids the local gathering of moisture, reaches the whole purpose of producing operation of protection circuit.
For achieving the above object, the utility model provides a kind of suspended insulated guide wire structure that blocks water, the cross section structure of this suspended insulated guide wire includes strengthening core, conductor layer, conductor shield and insulating barrier, wherein: the belting layer that vertically has been enclosed with resistance effect between every layer of described conductor layer.
Effect of the present utility model is to use the suspended insulated guide wire that blocks water of this structure, change original phenomenon of gathering moisture at the low ebb place of insulated conductor, thereby avoided the oxide etch of suspended insulated guide wire appearance for topic, reduce the maintenance cost of circuit, prolonged the useful life of suspended insulated guide wire.The utility model is applicable to rated voltage 1kV, 10kV and 35kV suspended insulated guide wire, equally also is applicable to the suspended insulated guide wire of not being with strengthening core.
Description of drawings
Fig. 1 is the suspended insulated guide wire cross section structure schematic diagram that blocks water of the present utility model.
Among the figure:
1, strengthening core 2, conductor 3, belting layer
4, conductor shield 5, insulating barrier
Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the suspended insulated guide wire structure that blocks water of the present utility model.
As shown in Figure 1, the cross section structure that the suspended insulated guide wire structure that blocks water of the present utility model is this suspended insulated guide wire includes strengthening core 1, conductor layer 2, conductor shield 4 and insulating barrier 5, vertically has been enclosed with the belting layer 3 of resistance effect between every layer of described conductor layer 2.Described belting layer 3 is banded waterstop, realizes block-water performance.The belting layer 3 that banded waterstop forms is to scribble the water-absorbing resin that expands at a high speed on polyester non-woven fabric.
The utility model is applicable to rated voltage 1kV, 10kV and 35kV suspended insulated guide wire, equally also is applicable to the suspended insulated guide wire of not being with strengthening core.
The suspended insulated guide wire structure that blocks water of the present utility model is achieved in that
The suspended insulated guide wire that blocks water of the present utility model, model specification are JKLGYJ-10kV 240/30, and its structure is followed successively by: strengthening core 1, conductor layer 2, vertical belting layer 3, conductor shield 4 and the insulating barrier 5 that has wrapped resistance effect.
The suspended insulated guide wire that blocks water of the present utility model, model specification are JKLYJ-1kV 1 * 240, and its structure is followed successively by: conductor layer 2, vertical belting layer 3 and the insulating barrier 5 that has wrapped resistance effect.
