36kv 5ka Polymer Surge Arrester Explosion Proof For Electricity Distribution

Product Description

36kv 5ka Polymer Surge Arrester Explosion Proof For Electricity Distribution

Quick Detail: 

36kV 5kA Distribution Types of Lightning Arrester

Product Description:

In General:

Polymer housed distribution lightning arrester is mainly applicable for protection of the power equipment like transformers against system over-voltages and lightning surges. It is manufactured with excellent voltage-ampere characteristics and high level of reliability and durability. And the arrester is designed and type tested according to IEC60099-4 standard.

Features & Advantages:

1. Simple structure ,small volume, light weight, the whole mould with no gas gap

2. Polymer Housed with flexible silicone rubber, explosion-proof.

3. ZnO varistor as the core component is subjected to a series of physical and electrical tests to ensure the reliability and protective ability.

4. Creepage distance is big, hydrophobic good, be able to bear or endure corrupt ability strong, stable performance, reduce operation maintenance

Operating Principl:

The metal oxide arrester provides the most advanced protection against over-voltage in the world,since MOA's resistors are made up of Zinc Oxide films.MOA has a good voltage-ampere characteristics as compared with silicon carbide arrester,it is Volt/Ampere characteristics is much superior and results in much better performance.

A micro ampere level current flows while MOA is operating under normal voltage, but the amount of the current will be thousands amperes when MOA is subjected to over-voltage, because of MOA has a good non-linear characteristics. Hence MOA provide excellent prection for the HV equipment, especailly the transformers, cables and switchgear.

Service Conditions:

1. Ambient temperature: -40°c ˜ +40°c

2. Height about sea level: ≤1000m

3. Power Supply frequency: 48-62 Hz

4. Earthquake intensity: Not exceed Richter 7.0 grade.

5. Maximum wind veiocity: ≤35m/s

6. The long-term power running voltage should not over the continus operating voltage.

7. The altiplano or Contaminated area should be indicated.

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.
