Product Description

Substation Voltage Lightning Arrester 51kv Light Surge Arrester Insulator

Quick Detail: 

Substation 51kv light arrester surge arrester insulator

OVERVIEW:
The metal oxidation arrester adopts an oxygen-zinc resistor with excellent nonlinear volt-ampere characteristics. Therefore, the protection characteristics of the lightning arrester, the lightning wave and the operating wave are greatly improved compared with the conventional silicon carbide arrester. In particular, the zinc oxide resistor has good slope response characteristics, no delay for steep slope voltage, low operating residual pressure, and no discharge dispersibility. Therefore, the disadvantages of the steep slope discharge voltage caused by the steep slope discharge delay inherent in the silicon carbide arrester, the large dispersion of the operating wave discharge and the high operating wave discharge voltage are overcome, so that the protection margin of the slope and the operation wave is greatly improved. Moreover, in terms of insulation coordination, it is possible to achieve a steep slope, lightning waves, and the protection margin of the operating wave is nearly uniform, thereby providing better protection for the power equipment, thereby improving the reliability of the protection. The zinc oxide surge arrester has the ability to absorb lightning overvoltage, operate overvoltage and power frequency transient overvoltage.

The composite jacket metal zinc oxide arrester is a high-tech product of the international 90s. It adopts integral silicone rubber molding, good sealing performance, excellent explosion-proof performance, pollution-free cleaning, and can reduce the occurrence of foggy wet flash, resistance to electric corrosion and aging, small size, light weight, collision resistance, easy to install and maintain. It is a new generation of porcelain sleeve arresters.

Technical Support

Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100 engineers. We have special pre-sales engineer to work with customer at early stage of the project.

 

 

Site assistance

Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia, Peru, Ecuador, Senegal, which will make a fast response for customer.

Warehouse and Emergency Supply

Warehouse and emergency supply for spare parts, damage parts and missing parts: DINGLI has built production line in Quito and warehouse for transmission line and distribution network in Ecuador, Bolivia and Senegal with common use spare parts.

Design and Consultant

Supported by both domestic engineering company and Quito tower design center, could provide technical consultant and design service within our scope of work. For Quito tower design center, most of the engineers are local staffs. The Design is based on ASTM protocols meantime with GB material standard, which will reduce the weight, and avoid the replacement on the profiles to save the working time.

Package

Set-wisely packing or member-wisely packing as per client's requirements.
