In the conditions of competitive struggle in world market of enterprises that produce copper winding enameled wires and goods on their basis the possibility of production realization considerably depends on its quality. That’s why the goal of PC “AKVATON” is a systematic support of production technology on such level that ensures stable high (every day and every hour) quality of production and also and maximally complete satisfaction of consumers demands concerning assortment of enamelled wires that are produced. It is provided by the fact that our enterprise tries to attain a worthy place in the market of enamel-wire with high heat resistance. We know that competitiveness depends, first of all on the ability of the enterprise for stable support and development of socially- demanded technical and technological level.
Also our goal is a constant increase of technical characteristics of produced goods and their reliability specifically by the search of new, high-efficient thermal, chemical and mechanical resistant insulation materials, their compounds, by the search of new and improvement of accepted technological processes in enameled wire production. This goal is achieved thorough examination of advanced experience in the field of cable-conductor production; personnel training and refresher courses for them; participation in international symposiums, conferences and exhibitions, carrying out of internal audits, Quality days, improvement of technological processes and design of elaborated goods.
The main components that provide high quality in our enterprise are:
I Quality Management System functioning according to International Standard ISO 9001-2008 that made it possible to reach a significant enterprise development rate and to solve a number of significant perspective tasks.
II. Modern equipment that allows providing production of enamel-wires with two-layer insulation system.
III Application of 8 mm copper wire rod, made according to Southwire Contirod or Dipforming methods with low oxygen content, namely 160-200 pm ≈ 300 ppm as a source material.
IV. Application of enamel-lacquers made by leading European firms as an electric insulation material. That’s why polyesteramide enameled wire produced by our enterprise by its heating resistance exceed all other existing types of enameled wires and temperature index of two-layer insulation constructions is 220 0C and more. Also, high elasticity, resistance to heat shock, good mechanical strength of enamel insulation, increased thermal plasticity, high resistance to solvents and coolants influence allows significantly extend the field of practical application of enameled wires produced by our enterprise, especially in electric engines, refrigerators and special engines production provided for work under hard climate conditions and winding of different household equipment, devices and goods.
V. Constant raw material, measuring units and equipment quality that are used in enameled wire production control is carried out in order to establish conformity of their quality to requirements of normative documentation and contract.
The control during the enamel-wire production process and ready production test are carried out according to Ukrainian technical norms: ГОСТ 21428-75 “Enameled round copper wires with temperature index 155, Technical Specifications”, ТУ У 27.3-13970259-001:2015 “Enameled round copper wires with enamel insulation on polyester or polyesterimide basis and external coating on polyamidimide basis, with temperature index 200” The control during production process includes the following:
- Technological process running (temperature control, annealing and enameling furnaces, wire motion rate, enameling machine operation temperature mode);
- Drawing emulsion control;
- Enamel-wire surface quality control.
Enamel-wire control center is equipped by modern import testing devices, attested by Rivne SE “Rivnestandardmetrology” (05.08.2004). It carried out the following enamel-wire quality control according to normative documentation:
- Wire segment mass control
- Wire constructive size control
- Adhesion test
- Insulation test by voltage
- Dot damage number test
- Relative elongation test
- Test of wire with diameter of 0.380 mm and more insulation for heat shock resistance
- Test of wire insulation for mechanical strength by attrition by the needle with diameter of 0.4 mm
- Elasticity test in initial condition (absence of cracks)
- Determination of tg δ – the loss vector tangent
- Test of wire elasticity
- Test of wires with diameter range of 0.06-0.355 mm insulation for heat shock resistance
- Test of wire insulation for mechanical strength by attrition by the needle with diameter of 0.4 mm after it has been treated with toluene
- Wire insulation test for thermal plasticity
VI. The qualified personnel of our enterprise, which executes all production, process operations at high professional level ensures a high production quality.
The quality of production in our enterprise is a quality of our life.
