Types of insulators used in high power transmissions

In the context of high power transmissions, the insulators are the support structures for wires and devices. The use of knobs and tube house wiring provides the flexible insulation. The HV power transmission use air as insulation or wires are buried in the ground for insulation.   Besides, these methods, there is no other economic way to insulate the HV lines. In transmission, the insulators are used to separate the wire from any structural support. The other reasons of using insulation is to stop the lighting from connecting the wires ,  and stop sparks or ground shots by not allowing the buildup of water , oil or dirt on the insulator . To prevent this kind of build up on insulators, they are designed in ridged form.

Wood and glass insulators were used initially as the insulators. Dry wood may be good insulator but it is not the perfect one. Glasses were used to insulatre telegram lines and telephone lines, as the electricity was used only for telephone and telegraph lines. However, these were only for low voltage currents.

Ceramics are used to Electrical BPL Kits Manufacturer  insulate the high power transmission lines and temperature. Glass insulators were not able to withstand high power and temperature. They would crack at the high temperatures. Initially the simple porcelain products were used as insulators. But later, for higher voltages, the new designs were made in existing porcelain products to enhance their performance with special coating.

Besides, these insulators, the many other common insulators used according to the requirements of the transmission of power and wires. The plastic has replaced rubber as insulation material for wires.  PVC, nylon and cresyl phthalate are the type of plastic that are used now in most type of wires.

Paper and cardboard are used today in some situations as they are cheap and can be used perfectly with high heat and high voltages. Mica is another good insulator and conductor .mica can be easily shaped and stamped for electrical components. This product is also used in many common capacitors.

Teflon is durable, slipper and have resistant to corrosion. This material is used in cables jackets. Teflon can come in many forms like FEP and ETFE.

PFA, Perfluoroalkoxy is considered better than PTFE in flexibility. It has resistant to chemical attack and is transparent.  The negative point of this material is that it cannot be folded unlimited number of times. The PFA is used near the sea shores, because it has resistant to salt spray. The dielectric strength of this material is 4 times higher than PTFE

Some non conductivity gases GI Strip Manufacturer in Delhi used to stop the formation of arc between two conductors in compact encapsulated metal container. Gas is also used in switch gears to disconnect two voltages safely. Some gas insulated transformers are also used.

Petroleum product is also used as an electrical insulator and heat conductor. The insulating oil can take heat away from transformer coil. Insulating oil is also used by some capacitors.

Issues faced by the power sector in India

Most of the power produce comes from the thermal power plants and the coal is the main fuel used in these plants. The quality of the coal from Indian is of low that is why the coal has to be imported from foreign countries.   The use of coal also adds to the air pollution and environmental issues.

Efforts are on to reduce the dependence on coal and increase the power generation from other sources such as wind energy, nuclear and solar energy. But still the major share of power comes from thermal power plants .The coal handling and ash handling is another issue that is faced by the thermal power plants.

The large electrical items that are used in the power plants are imported from other countries. The local manufacturing facilities are not able to meet the demand of the plants. The shortage is not only in the boilers, generators or turbines but also in small items like switches as well.

Land acquisition is a politically sensitive issue in the power plant construction. Since power plants are constructed in the far flung areas and often include agriculture lands.  The farmers lobby works against the land acquisition and then get the support of opposition political parties. The government cannot avoid the opinion of these people as often they decide the electoral success of political parties. This delays the implementation of power project policies.  Even if the land is taken for power projects, then getting environmental clearance take months and sometimes the issue can go for years. The new land acquisition bill continues to face tough opposition from almost all political parties. No political party wants to damage its election prospects by going with the land acquisition bill. When government is not able to get the land for power plants, the private companies also do not want to take the chance to come in investment proposals in power sector.

High distribution and transmission losses are one of the major problems affecting Indian power industry. These huge losses can reduce the gap between demand and supply. Saving of 1% of these losses can add 800 MW power generations.

Obsolete plants and Electrical BPL Kits Manufacturer transmissions lines increase the losses and cannot take the load during peak hours. This is one of the reasons for the low growth electricity generation and transmission. In recent years the demand for electricity has increased manifolds in the country. The government is trying to have more nuclear plants for power generation. The only concern with the nuclear power plants is that the spent fuel needs to be handled cautiously.

The hydro electric projects GI Strip Manufacturer in Delhi cannot be constructed at every river because of erratic   behavior of monsoon and dry spell which country faces from time to time.  Also interstate disputes on river water flow and sharing of river water practically do not support the construction of dams across river connecting more than one state.
