Abstract
The utility model belongs to the technical field of an electric power system safety device, relates to a grounding wire and especially relates to a zinc clad steel grounding wire. The zinc clad steel grounding wire comprises a steel core (1) and a zinc layer (2) wrapped at an outer side of the steel core (1), wherein thickness of the zinc layer (2) is 0.5mm to 20.0mm, the zinc layer (2) is wrapped at the outer side of the steel core (1) through electroforming, electroplating, cladding or continuous casting. According to the zinc clad steel grounding wire, the zinc layer is relatively thick, so external chemical corrosion resistance is strong during use of the zinc clad steel grounding wire, and electrical corrosion can be effectively alleviated, and thereby service life of grounding materials is greatly prolonged, and the zinc clad steel grounding wire has great application prospects in the technical field of the electric power system safety device.
Description
Technical field
The utility model belongs to power system security device technology field, relates to a kind of earth connection, relates in particular to a kind of zinc Baogang earth connection.
Background technology
Traditionally, the lightning protection line adopts be fine copper or clean steel material as lightning-proof grounding body, because potential difference produces galvano-cautery greatly, make the earth connection life-span shorten, the potential difference of zinc and steel is less, the galvano-cautery effect is less.And in prior art; galvanized steel adopts the form of hot galvanizing or electrogalvanizing to adhere to one deck zinc in steel core surface more; the thinner thickness of zinc layer; be only 40-70 μ m, in use, protective layer is corroded very soon; cause the earthing material lifetime; thereby cause lightning disturbance, personal safety can not get ensureing, also causes larger economic loss.Because the cathodic protection steel core is less, as earth electrode, its mechanical strength and thermal stability are lower, and conductive capability is little, can not satisfy code requirement simultaneously.
Summary of the invention
The purpose of this utility model is that to overcome in prior art the zinc layer thinner, in use easily be corroded, cause the defective of earthing material lifetime, provide a kind of zinc layer thicker, in use except the chemical corrosion in the anti-external world, galvano-cautery can also effectively be slowed down, the zinc Baogang earth connection that makes that the earthing material life-span lengthens greatly.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of zinc Baogang earth connection comprises steel core and is wrapped in the zinc layer in the steel core outside that zinc coating thickness is 0.5～20.0mm.The zinc layer reaches 1.0mm when above, and earth connection of the present utility model in use except the chemical corrosion in the anti-external world, can also effectively slow down galvano-cautery, and the earthing material life-span is lengthened greatly.In cathodic protection engineering, it does not affect the cathodic protection of building itself, if building is not installed cathodic protection, it can be because of cause the galvano-cautery of building grounding system as earthing conductor yet.
As preferably, the thickness of zinc layer further is chosen as 1.0～12.0mm.
As preferably, the zinc layer is wrapped in the steel core outside by electroforming or plating or coating or continuous casting.Electroforming or plating or coating or continuous casting all can be integral steel core and the combination of zinc layer, and performance advantage separately, be greatly enhanced the combination property of earth connection mutually.
The utility model discloses a kind of zinc layer thicker, in use except the chemical corrosion in the anti-external world, can also effectively slow down galvano-cautery, the zinc Baogang earth connection that makes that the earthing material life-span lengthens greatly.The utility model has good application prospect in power system security device technology field.
Description of drawings
Fig. 1 is the structural representation of a kind of zinc described in the utility model Baogang earth connection.
In figure: 1-steel core, 2-zinc layer.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment
A kind of zinc Baogang earth connection as shown in Figure 1, comprises steel core 1 and is wrapped in the zinc layer 2 in steel core 1 outside.
The thickness of zinc layer 2 is 8.0mm.
In a word, the above is only preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
