Abstract

The utility model discloses a novel large-capacity low-sag pre-tension wire, which comprises a core wire and a conductive bare wire which is coated outside; the core wire is a stranded galvanized steel wire, the conductive bare wire is a plurality of layers of aluminum wire stranded outside the core wire. The maximum working temperature of the novel large-capacity low-sag pre-tension wire is increased, and the current-carrying capacity is improved, and the transmission cost is reduced. Moreover, the sag and the weight of the novel large-capacity low-sag pre-tension wire are reduced when compared with the bare wire in the present transmission and distribution line; the laying installation can completely utilize the present tower resource, and the tower cost can be reduced.

Description

A kind of novel big capacity low arc drop pre-stretching lead
Technical field
The utility model relates to a kind of lead, especially the plain conductor of transmission of electric energy in the electric line.
Background technology
The plain conductor of transmission of electric energy in the existing electric line, because aspects such as its structures, maximum operating temperature has only about 90 ℃, thereby its current capacity is subjected to severely restricts.
Summary of the invention
In order to overcome the deficiency of the plain conductor of transmission of electric energy in the existing electric line, the utility model provides a kind of novel big capacity low arc drop pre-stretching lead, its maximum operating temperature can reach about 150 ℃, can bear and carry big capacity electric energy, and lead can be realized low arc drop after setting up.
A kind of novel big capacity low arc drop pre-stretching lead that the utility model provides comprises the conduction bare wire of heart yearn and outsourcing, and heart yearn is the galvanized steel wire of strands, and the conduction bare wire is several layers and is stranded in the outer aluminium alloy conductors of heart yearn.
Several layers of aluminium alloy conductor that is stranded in outside the heart yearn of the present utility model can carry out pre-stretching when stranded, make it longer than heart yearn, thereby have certain slackness with respect to heart yearn.
The beneficial effects of the utility model are: its maximum operating temperature improves, and can reach about 150 ℃, and therefore, current capacity increases, and can reduce the transmission of electricity cost.And the plain conductor in the existing electric line of its sag and weight ratio reduces, and laying installation can utilize existing shaft tower resource fully, reduces the shaft tower cost.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, heart yearn, 2, the conduction bare wire.
Embodiment
With reference to Fig. 1, earlier several galvanized steel wires are twisted into heart yearn 1, the logarithm layer is stranded in heart yearn 1 outer aluminium alloy conductor and carries out pre-stretching again, will be stranded in through several layers of aluminium alloy conductor of pre-stretching outside the heart yearn 1 then, form several layers of conduction bare wire 2, promptly make the utility model.

Claims (1)

1. novel big capacity low arc drop pre-stretching lead comprises the conduction bare wire of heart yearn and outsourcing it is characterized in that heart yearn is the galvanized steel wire of strands that the conduction bare wire is several layers and is stranded in the outer aluminium alloy conductors of heart yearn.
