Zinc layer 3mm Zinc coated steel composite grounding rod 1mm Zinc coated steel grounding wire Zinc coated steel grounding electrode

Description :

Zinc coated steel grounding wireIt is a new type of grounding product, and the zinc clad steel grounding wire has advanced horizontal continuous casting technology in China. The cleaned low-carbon steel core is heated to a higher temperature, and the zinc ingot is melted by using a power frequency furnace. The steel core is quickly passed through the zinc liquid and crystallized at the outlet to form a bimetallic composite of zinc clad steel, which is then drawn and processed into a zinc clad steel grounding rod.

1、 The advantages of zinc coated steel grounding wire:

　　1. Unique manufacturing process: Adopting advanced domestic horizontal continuous casting technology to achieve molecular bonding between zinc and steel.

　　2. The thick zinc layer has excellent anti-corrosion properties: with a service life of up to 50 years, it overcomes the problem of short service life caused by corrosion in traditional flat steel and round steel grounding.

　　3. No electrical corrosion: It has a positive effect on the cathodic protection of equipment.

　　4. Good conductivity: 2.5 times the conductivity of steel core, with stable electrical performance.

　　5. Simultaneously solving the two major issues of cathodic protection and lightning protection grounding at once greatly reduces engineering investment and construction costs.

　　6. The zinc coated steel grounding wire uses low-carbon steel as the steel core, which has the strength and thermal stability of steel, ensuring the grounding leakage function.

2、 Application areas of zinc coated steel grounding wire:

　　With the extensive construction of urban power infrastructure projects, grounding devices play an important role in safety protection, and their reliability has been increasingly valued. The use of ordinary angle steel, galvanized flat steel or building foundation steel bars as grounding bodies affects the reliability of the grounding device due to poor corrosion resistance. The grounding resistance increases continuously with the corrosion of the grounding body, resulting in poor stability and a short service life (usually a few years). It also needs to be tested and maintained annually, with a large workload and high subsequent construction and maintenance costs. In places where steel equipment is present in grounding areas such as petrochemicals, urban power facilities, and some power plants, it can cause corrosion damage to other buried steel structures. Both cathodic protection and grounding have been used simultaneously both domestically and internationally. The use of zinc clad steel composite materials as grounding bodies and lightning conductors, due to the thick zinc layer, can effectively prevent corrosion of the grounding electrode, thereby increasing its service life. At the same time, it can also solve the cathodic protection problem of pipelines and other steel equipment. It can be seen that zinc clad steel composite grounding electrodes can be widely used in grounding. Cathodic protection can also be used as grounding material for other buried steel structures in situations where cathodic protection is present and soil corrosiveness is strong.
