Introduction

According to the global climate change issue, many utilities and the Public Limited Companies are planning to grow more and more trees and living friendly with animal such as birds, squirrels, etc. These cause a lot of electricity blackouts mainly to the overhead line power distribution system, other causes from lightning, strong wind, raining, chemical pollution and trees themselves. Each time of blackout, it costs utility not only a large amount of expense but also the reputable of reliability will be questioned and lead to the compensation and exchanging of the electricity supplier.


In conventional overhead 12-33 kV distribution construction system, it is clearly seen that most of the terminal points for electricity path are not completely covered with outdoor insulation products, so we offer a complete ranges of barriers / deterrents / insulation, cost effective, and reliable means to protect their substation and overhead line assets from bird, squirrels, snakes and other environmentally induced flashovers such as lightning and tree touching, etc. The material shall be specified all types of polymer which are designed and tested to be quick installation, no special tools, UV stable, non-tracking, abrasion resistant and high dielectric strength withstand.


The Thai electricity utility has been proving our products and confirms to improve service level, reduce the environmental risk, maintain customer satisfaction and increase equipment life expectancy which leads to protect his own expensive assets.
