Introduction
Electrical Porcelain and L.T. Insulators are of semi vitreous body. These products are in a position to withstand normal domestic voltage up to 440 volts. Glazed products are made for use in exposed weather and unglazed products are used in dry conditions. The main types of product(s) are: LT insulators, shackle insulators, split insulators, kit-kats, outlet boxes, switch boxes, connectors, plugs, sockets, lamp holders, bushes, cleats, label racks, bobbins etc.
They are used in telephone and power supply to houses and other electric applications like electric iron, toasters, stabilisers, transmission and distribution of power line at low voltage 220-440 volts in the telephone and telegraphic lines.
Market Potential
Due to developmental projects of Govt. of India and States for electrification of rural and urban areas in the country, the demand of these items and products is increasing day by day. The growth rate is anticipated to be around 15% per annum. The porcelain insulators are used in L.T. Electrical energy distribution systems and telegraphic communication system wherein these items are consumed for new erection and replacement by the State Electricity Boards, P&T Department, Railways etc. and private sector companies.
The demand of various types of insulators also exists due to upsurge in the building construction activities by private enterprises, societies and builders. The use of electrical appliances is also increasing. These factors contribute to the increased demand of various types of ceramic insulating material in the domestic market. The industry has successfully tapped export market as well. Hence there is a good scope to set up this industry in the SSI sector.
Basis and Presumptions
By considering that the unit will work on single shift basis for 300 days in a year. However, the firing will carry out continuously on three-shift basis till particular firing cycle is completed in all aspects.
Margin money will vary from 10-25% depending upon the location and scheme adopted by the entrepreneurs. Labour and wages are taken as per the prescribed minimum wages of Govt.
To achieve full plant capacity 1-2 months of production trial is necessary.
The costs of land, construction charges, machinery and equipment, raw materials and consumables, other contingent expenses etc. is taken in the profile as per prices prevailing in the market at the time of preparation.
Operative period of the project is around 10 years considering technology obsolescence rate and period of replacement of loan.

Technical Aspects
Process of Manufacture
Main raw materials like china clay, ball clay, quartz, felspar, plastic fire clay are used for the preparation of body. Materials like whiting, barium carbonate, zinc oxide etc. are used for the preparation of glazes. The non-plastic raw materials are ground in ball mill to the fineness of 100-120 number mesh and water is added in desired proportion. China clay and other soft clays with 0- 40% water are blunged in the blunger and sieved through 120 No. mesh and then passed through electromagnet in order to remove the iron particles.
Both slurries are mixed proportionately in the agitator tank. The slurry from the agitator tank is passed through filter press for dewatering to make cakes. L.T. Insulators like pin, shackles etc. are made by pressing or throwing process followed by turning on leather hardening.
For making the electrical pressed porcelain items, the cakes are dried and powdered in a disintegrator. Dry broken green articles are also mixed with this body with approx. 6% water and 3% oil is mixed to form consistent and uniform granules. The prepared mass is again passed through a sieve granulator, so that any lump formed during mixing is broken to form granules.
The mass is then pressed into shapes in a piller press/toggle press fitted with dies of desired shapes. The articles are then dried and finished. The articles are glazed, if required and then fired at the temperature of about 1280 oC in a shuttle kiln. The articles are taken out from the kiln are sorted and packed for selling.
Quality Control and Standards
The BIS has formulated and published IS 1445:1977 and IS 283:1976 for carrying out the various tests and specifications which may be used as basis for quality control.
Production Capacity
Quantity | : 900 MT |
Value | : Rs. 1,04,40,000. |
Motive Power | 85 HP. |
Pollution Control
Cyclonic dust collector to be installed to control the airborne dust during the crushing. The Kiln should conform to the specification to ensure clean operation as per the Pollution Control Act.
Energy Conservation
Industry needs energy conservation in fuel as well as in power consumption. The use of ceramic fibre in the shuttle kiln conserves 20-40% of fuel energy compared to conventional type of D.D. Kiln.
