Abstract
The utility model discloses a kind of ultra-high-tension power transmission line down conductor, it comprises one section of GJ-100 type galvanized strand wires, and galvanized strand wires two ends adopt crimping mode to be connected with crimp type terminal.The utility model selects GJ-100 type galvanized strand wires to replace existing galvanized steel bar or zinc-plated band iron, because GJ-100 type galvanized strand wires sectional area is larger, further reduction resistivity, pliability is better simultaneously, corrosion resistance is strong, and the ability that resistance to mechanical is destroyed is comparatively strong, is not only easy to earthing device construction, and reduce earthing device and damage the economic loss caused, improve economic benefit.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line, particularly relates to high-voltage transmission line pole tower down conductor.
Background technology
Ultra-high-tension power transmission line particularly 35KV and above transmission line all requires that shaft tower is by the direct ground connection of base in the design, and the quality of earthing device directly has influence on the height of earth resistance, and then determines that thunder and lightning or overcurrent are imported the performance of the earth by transmission line.At present, the many employings of down conductor of high-voltage transmission line pole tower and earth electrode are with the galvanized steel bar of material or zinc-plated band iron, but overhead line structures are all in arable land, field, down conductor is easy to be corroded and gets rusty and often suffer outside destroy, once tower grounding device destroys, when shaft tower thunderbolt, earial drainage can cause circuit overcurrent tripping accident impact electricity consumption enterprise safety operation not in time.
Summary of the invention
The purpose of this utility model is for solving the problem, and designs a kind of corrosion resistance strong, the ultra-high-tension power transmission line down conductor that resistance to mechanical outside destroy ability is strong.
The utility model solves the technical scheme that its technical problem adopts:
A kind of ultra-high-tension power transmission line down conductor, it is characterized in that, it comprises one section of GJ-100 type galvanized strand wires, and galvanized strand wires two ends adopt crimping mode to be connected with crimp type terminal.
During use, be connected between earth electrode and shaft tower with the bolt of band spring pad and plain cushion by down conductor of the present utility model, with bolt crimping, contact-making surface can not leave gap.
The utility model selects GJ-100 type galvanized strand wires to replace existing galvanized steel bar or zinc-plated band iron, because GJ-100 type galvanized strand wires sectional area is larger, further reduction resistivity, pliability is better simultaneously, corrosion resistance is strong, and the ability that resistance to mechanical is destroyed is comparatively strong, is not only easy to earthing device construction, and reduce earthing device and damage the economic loss caused, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of ultra-high-tension power transmission line down conductor, it comprises one section of GJ-100 type galvanized strand wires 1, and galvanized strand wires 1 two ends adopt crimping mode to be connected with crimp type terminal 2.
Be connected between earth electrode and shaft tower with the bolt of band spring pad and plain cushion by down conductor during use, with bolt crimping, contact-making surface can not leave gap.
