About products

Winding wires are wires used for manufacturing windings of electrical machines, devices, and instruments, produced in accordance with GOST 21428-75. A significant amount of winding wires is also utilized in the production of instruments, various radio engineering devices, televisions, aviation and space technology, and more.

PET-155 and PEEA-155 are round enamelled copper and aluminum wires with a temperature index of 155°C.

Enameled wire made of copper (PET-155) or aluminum (PEEA-155) features insulation based on varnishes. For PET-155 and PEEA-155, polyester, polyurethane, and polyvinyl acetal varnishes are used to achieve a high-strength and wear-resistant enamel coating. The resulting insulation is characterized by a high degree of elasticity, excellent protective properties, and superior electrical insulation capabilities.

The wire insulation is resistant to:

• thermal shock at a temperature of 155 ± 5°С.

Key features:

• High strength with a small cross-section and excellent flexibility;
• Outstanding electrical conductivity and good thermal conductivity;
• Ability to maintain operational characteristics across a wide temperature range;
• Stable electrical resistance throughout its service life;

The diameter of the winding wire ranges from 0.90 to 2.50 mm, and it is shipped wound on spools.
