Insulator TR202 with Plastic Barrier for high-voltage systems

Electrical insulators are among the most important components for both low- and high-voltage power distribution systems, because they determine the safety and stability of the current delivered to homes, factories, and various projects. Using substandard equipment, or equipment unsuited to the site conditions, can cause short circuits, flickering, or blackouts from unexpected causes such as birds, squirrels, or branches blown onto the wires.

One of the widely popular models for high-voltage electrical work is the Insulator TR202 with Plastic Barrier, an important device in power transmission and distribution systems that also increases safety and efficiently reduces blackout problems, especially in areas with abundant animals or many trees.

Insulator TR202 What does it do?

An electrical insulator may look like a small device, but it actually plays a more important role in the safety of the electrical system than many people think. The TR202 functions consist of 3 main parts, as follows:

1. Acts as electrical insulation (Electrical Insulation)

In power distribution work, the insulator separates the electrical potential between the wire and the structural pole, to prevent current from flowing to ground or causing flashover, which could cause an area blackout. The Insulator TR202 is therefore designed with a high creepage distance and a special surface coating, effectively reducing the chance of tracking.

2. Supports the tension and mechanical loads of the wire (Mechanical Support)

When used outdoors, high-voltage wires generate tension according to weight and span length, and the insulator must bear these loads continuously. The TR202 can withstand tension of up to 12 kN, making it suitable for installation in windy areas or areas with long spans.

3. Increases safety when used together with the Plastic Barrier

In Thailand, frequent blackouts are often caused by animals climbing the poles or branches blowing onto the wires. The Insulator TR202 that comes with the Plastic Barrier helps create an additional protective layer, reducing contact reaching through to the insulator and wire, greatly reducing short-circuit problems — especially in factory areas and communities where birds or squirrels live. 

Insulator TR202 with Barrier — what applications is it suited for? ?

The Insulator TR202 with Barrier is very suitable for installation in communities with many trees, or areas with abundant birds, because its Barrier plate helps prevent accidents from animals or branches that may touch the wires, reducing voltage-drop and blackout problems that can arise from these causes, so the community has continuous electricity without worrying about sudden blackouts. It is therefore popular in many areas, for example:

• Communities with many trees
• Industrial factories with many reptiles or birds
• Product warehouses, rice mills, and open areas
• Rural electrical systems at risk from blowing branches
• Power distribution maintenance work aiming to reduce blackouts

How to buy the Insulator TR202 with Animal Barrier at a good price and suited to your work

When buying the Insulator TR202, you must consider the price together with various factors to get the model that best matches the specifications and is safest.

• Choose by voltage level: Check whether your system uses 22 or 33 kV to choose a suitably rated specification.
• Choose by site environment: In cities with little pollution, a standard type can be used; but near the sea or factories, choose a model with a special surface coating that resists high pollution, to reduce tracking.
• Check product standards: It must have TIS or IEC standards for the safety of the electrical system and operators.
• Choose a distributor that keeps stock and can genuinely advise: such as TETA INTERTRADE, ready to advise through experts and ship products quickly nationwide.
