Product Description

11kv 12kv High Voltage Metal Oxide Polymer Surge Protector Lightning Arrester

Product Description:

The zinc oxide arrester is the most advanced over-voltage protector in the world, Due to make the resistor

disc of core component mainly adopt zine oxide arrester. Compared with the conventional silicon carbide

arrester, this prescription of the product improves greatly the volt-Ampere characteristics of the resistor disc

and increased through-current capability at over-voltage so as to dring radical changes for the characteristics

of the arresters.
Under the circumstance of normal operating voltage, the current through the arrester is just on microampere

degree, When suffered from over-voltage, the arrester's excellent nonlinear characteristics will make the current

through the arrester increase to several thousand amperes, while the arrester will be under the circulating state

and release over-voltage energy so as to protect the power transmission equipment against the damage caused

by the over-voltage.

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.
