The insulation of transmission gears is made of polymers these days. In the past, glass or ceramics were usually used for insulations. Previously, polymeric insulators were used only in certain urban areas, to defend them from high pollution levels and sabotage risks. Now, these insulators are being used for nearly all power levels, and they are also called composite insulators. This insulator can easily obtainable from the composite polymer insulator suppliers in India.
Benefits of the composite polymer insulator
Lightweight - Different from the traditional glass ones, polymer insulators are so light in weight and compact. This makes it simple to fit them into smaller cranes. It also gives better clearance space between the ground and the conductor. Being lightweight, they are calm to install and sustain.
Hydrophobic - These devices are extremely water-resistant. Their hydrophobic properties stop the accumulation of water on the surface of the insulator, which in turn stops flashovers and surface currents.
Higher Mechanical Strength - Polymer insulators keep great mechanical strength, due to which the transmission towers can be simply sited, situated at farther distances. Generally, as the traditional insulators have low mechanical strength, it bounds the transmission capability of the tower and the power productivity as well. Today, with such devices, it is easier to shelter superior areas without productivity being impacted.
Pollution-resistant - One of the prime benefits of polymer insulators is that they are pollution resistant in nature. They preserve from the dirt, dust and water away, thereby comforting no internal or external damages or malfunction.
Due to this, the cost involved in preserving and cleaning these devices is ominously low. They are appropriate in areas with higher pollution levels, and where their consistent maintenance is not feasible.
Is polymer insulators are reliable?
Whether it's a ceramic or composite insulator, the dependability of the device is one of the most significant things that you need to study while buying it. The toughness depends on its mechanical and electrical properties. Today, with the assistance of modern manufacturing techniques and hi-tech fixture, composite insulator manufacturers can prominently improve the mechanical strength of composite insulators. Innovative composite devices were presented in the market a couple of decades ago, and the version, which is presently being used, was launched almost 13 years ago.
These devices have a fibre-rod-like structure, which is closed with precise weather-resistant materials, generally rubbers and fillers. The end fixtures are then attached to the whole assembly. One of the utmost significant things to be considered with these insulators is the gap or clearance or interface between air and solid insulating body.
Most of the times, the core issue appears at the interface, as this is the spot where the solid insulator and air incline to hold up. Besides, the negative impact of pollution, water buildup and dirt, etc. lead to outflow in the current supply and worsen the overall performance of the installation.
Thus, to recover performance and efficiency, composite polymer insulators are enclosed with heavy-duty materials on the inside of the polyester core rod.
