glass insulator production shop
Glass insulator production shop produces high-voltage overhead line insulatorsof various types withstanding mechanical failing load from 40 kN to 530 kNincompliance with the State and international standards requirements. Toughened orannealed glass is used as insulating material which has a high insulating properties,mechanical strength, thermal and chemical stability.
According to the customer requirements for areas with the high air pollutions,factory produces insulators using pins equipped with zinc sleeves, being the"sacrificial electrode" which prevent for a long time the corrosion caused by DCand the environment.
Thermal treatment of glass (hardening) provides high mechanical and electricalproperties and thermal strength of the insulator. After subsequent thermal testsdefective items are rejected. It guarantees the specified characteristics of insulators.
After thermal tests all glass parts are subjected to the visual inspection andverification of dimensions.
After the assembly of glass insulators routine mechanical and electrical tests arecarried out.
In 2007, Steep wave front (puncture in air) tests were carried out to meet thestandard requirements of IEC 61211:2004.

ОАО "YuAIZ" (Yuzhnouralsky Insulators and Fittings Plant)Yuzhnouralsky Insulators and Fittings Plant was founded in 1957 and now is anunique enterprise in the energy sector, uniting on the same area a few productionfacilities: glass insulator production, ceramic insulator production, forging andcasting workshops.
In 1996, the quality management system was established on the factory inaccordance with ISO 9001, and in 2009 its systematical development enabledthe confirmation of compliance with the new version of ISO 9001:2008requirements. YuAIZ testing center has an accreditation with the FederalAgency for Technical Regulation and Metrology, and meets requirementsof the Russian State standard GOST R and the international standard ISO/IEC17025:2006, ISO/IEC 17025:2005.
Within the investment program in 2006 the new glass furnace was constructedat the factory. In the beginning of 2008 the WALTEC production line for themanufacturing of glass insulating parts was put into operation. Today thecomprehensive modernization process of the enterprise is continuing.
The production of YuAIZ is subjected to type and periodical tests in independentnational and international test centres. Factory has the possibility to carry outadditional tests according to the special requirements of the customers.
Lviv Insulator Company Ltd. ("LIC" Ltd.)The Lviv plant manufacturing high-voltage insulators made of toughened andannealed glass was founded in 1965.
In 2011 the production modernization was brought into force at LIC: the newglass furnace has been constructed and a modern production line for manu-facturing of glass insulators has been installed. The modernization of productionhas enhanced the enterprise efficiency, increased the product competitivenessin the global market. The advanced equipment WALTEC allowed the companyto manufacture products according to international standards.
More than 260 mln pieces of insulators manufactured in Lviv Insulator Plantover the years of its activity, have been successfully operated on lines withvoltage from 0.4 to 1150 kV in power systems of more than 40 countriesaround the world, that is proof positive of perfect quality and high perform-ance reliability of Lviv insulators.
"LIC" Ltd. has the own testing laboratory certificated by Federal Agency onTechnical Regulating and Metrology of Ukraine where each batch of themanufactured products is subjected to acceptance tests.
Lviv Insulator Company has a certified quality management system in productionand marketing of electrical glass insulators in accordance with ISO 9001:2008.
Advantageous geopolitical location on the border with Europe, numerousroad and rail routes and closeness to the sea lines allows LIC to supply productsto any part of the World.

Acc. to ANSI C 29.1 there are possible the tolerances in values:
· dry power frequency flashover voltage ±5% (average flashover value at testing on three strings will be equal or higher than95% from the value shown in the table),
· wet power frequency flashover voltage ±10% (average flashover value at testing on three strings will be equal or higherthan 90% from the value shown in the table),
· critical impulse flashover voltage ±8% (average flashover value at testing on three strings will be equal or higher than 92%from the value shown in the table).

glass insulators
The characteristics of insulators with a zinc sleeve fully correspond to those ofinsulators without it. The zinc sleeve, being "a sacrificial electrode", prevents fora long time from corrosion of a pin caused by d.c. and environmental conditions(a tropical climate).
When the insulators are stored in a dry atmosphere, especially at high temperature,the cement bond loses its moisture. It resulted in a slight shrinkage, in this caseincreases the clearance between the glass and cement bond. In some cases theincreased clearance can lead to a rotation of the pin relative to the glass by afew degrees. This rotation arises from the manual effort with characteristic clickingnoise. This phenomenon disappears once you move the insulator into the atmospherewith normal conditions or being under load when assembling on the line. Thisphenomenon does not affect an insulator performance.

The plant manufactures insulators with W-clips and split-pins, which corresponds to the Russian and international standards.Split-pin provides more reliable coupling in a string, as the cross-section area of the split-pin is 2 times more than the cross-section area of the W-clip. The insertion of split-pins and bending of the legs are made at the plant.It is necessary to note, that with such a universal coupling it is possible to make a string of insulator units with different typesof locking devices.

Packingpacking
The advantages of this type of slattedcrate:Convenience of disassambly (box doesnot require special tools to open it: onlyuntwist the wire and box is opened).During transportation empty boxes laidout in crate and to take up a little spacein the truck.
Each packet with crates includes severalwooden crates placed on the pallet.For packing manufacture the "screw-ringed" nails are used. They have ringgrooves on the stem that create the addi-tional friction force and the nails keepthe nailed timber more fixedly.The pallet packer wraps round the packetwith insulators by strechtape in a fewlayers to strengthen it for transport tothe consumer.
The pallet packer wraps round the packetwith insulators by strechtape in a fewlayers to strengthen it for transport tothe consumer.
The packing of insulators supplied by GIG is made of wood treated in accordance with the international standard ISPM-15.When the insulators are stored at the open storage ground, the wood may darken under ultraviolet exploration or dust.The impact of these factors on the packaging material does not reduce its mechanical strength.
