Product Description

High Voltage Surge Arrester And Lightning Arrester Used In Substation 66kv

Quick Detail: 

High Voltage Substation Lightning Arresters Manufacturers of 66kV Surge Arrester

OVERVIEW:

0.25kV~750kV Surge Arresters' Characteristics:
1. The Core column applied winding structure, Polymer Housed core pillar molded on the core column, with almost no internal air gap, and outstanding sealing performance Simple in structure, small in size and light in weight.
2. Polymer Housed with silicone rubber, explosion-proof ZnO varistor as the core component is large
in flow capacity.
3. International standard IEC 60099-4 and ANSI 62.22, and with high reliability. With fully insulated tops, the product can be applied to the complete cabinet installation, which can reduce the designing size of cabinet.
4. Products with detachment device can provide signals for quitting operation when failure occurs,
avoiding arrester explosion, and it is maintenance-free.
5. Polymer housed products with a six CTI level, creepage distance meets the requirements of IV level in heavy pollution areas.

1. About us

HENAN DINGLI was founded in 1963 as a small electric power equipment manufacturer, after more than 50 years’development, DINGLI now is group company dedicated on total solutions for electricity projects covering survey, design, manufacture, complete equipment supply, construction, operations, maintenance, investment and so on. HENAN DINGLI actively devote to power grid construction, participated in all UHV construction projects and made an outstanding contribution to UHV transmission lines of China.

 

Since 2000, HENAN DINGLI has been actively developing international business, successively built Ecuador, Cambodia manufacturing Base, Quito tower design center, Spain, Peru, Chile and other overseas service centers. We have got a number of international certificates, such as ISO certificate covering design, equipment and construction, AWS welding certificate, ASTM system certificate, Chile NCH 203 certificate, Colombia RETIE certificate, Costa Rica material quality Certificate, etc. By the end of 2018, the overall proportion of international business is more than 30% of the company's main revenue. We have provided high-quality products and services to more than 100 customers in 33 countries, including the markets of Europe, America, Africa and Southeast Asia. With strong technical support and on-site service capability, HENAN DINGLI has saved a lot of project costs for customers and won their recognition.

3. After-Sale Service

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.
