Motor-and-tractor wires with polyvinylchloride insulation (hereinafter - "wires") are designed for motor-and-tractor equipment connection to electrical equipment with rated voltage up to 28 V, manufactured for vehicles designed for usage in moderate, tropical and frigid climate.
Wire models, their primary operation area and temperature range of usage as components of harnesses and armored cables correspond to the requirements given in the table below:
| Model | Definition | Primary operation area | temperature range of usage °С |
| PVA | Wire of high flexibility with copper conductor, polyvinylchloride (PVC) insulated, single-wired, heat-resistant | Motor-and-tractor equipment and devices requiring high connection flexibility and operating at high temperatures | from -40°С to +105°С |
| PVAE | Wire of high flexibility with copper conductor, polyvinylchloride (PVC) insulated, single-wired, heat-resistant, shielded | The same as above but additionally requiring wire shielding | The same |
| PVAMDE | Wire of high flexibility with copper conductors, polyvinylchloride insulated, double-wired, shielded, with polyvinylchloridesheath, heat-resistant | The same as above but additionally requiring wire shielding | The same |
| PGVA | Wire of high flexibility with copper conductor, PVC insulated, single-wired | For motor-and-tractor equipment connection to electrical devices and equipment | from -40°С(from -60°С in compliance with ХЛ1) to +80°С |
| PGVAE | Wire of high flexibility with copper conductor, PVC insulated, single-wired, shielded | The same as above but additionally requiring wire shielding | Thesame |
| PGVAng(S) | Flexible wirewithcopperconductor, PVCinsulated, fire-resistant,single-wired | For motor-and-tractor equipment connection to electrical devices and equipment | from -40°С to +70°С |
| PGVAEng(S) | Flexible wirewithcopperconductor, PVCinsulated, fire-resistant,single-wired, shielded | The same as above but additionally requiring wire shielding | Thesame |
| PGVAM | Flexible wire with copper conductor, PVC thin-wall insulated, single-wired | For motor-and-tractor equipment connection to electrical devices and equipment | from -40°С to +80°С |
CONDUCTOR:copper, stranded.
INSULATION:for PGVA, PGVAM, PGVAE models- PVC compound;
for PVA, PVAE, PVAMDE, PVAM -1 models - heat-resistant PVC compound;
for PGVA, PGVAE modelsofХЛ1 type -frost-resistant PVC compound;
for PGVAng(S), PGVAEng(S) models- fire-resistant PVCcompound.
For PVA Мand PGVAM models thin-wall insulation is used. Wire insulation can have solid color or combined color (by order). Combined coloring is performed by combining parallel strips of two colors, one of which is basic. There should be one or two secondary colorstrips.
SHIELDING:in wires of PVAE, PGVAE и PGVAEng(S) models the insulated conductors are covered with shielding - braiding with copper wire of 0.12 mmto 0.26 mm rated diameter, tinned with tin-lead solder. For PGVAE, PVAE и PGVAEng(S) models of type Т1 the shielding copper wire is tinned with tin solder. PVAMDE model shielding consists of braiding or winding of copper wire or winding with foiledpolyethyleneterephthalate (lavsan) tape covering.
NUMBER OF CONDUCTORS:1. For PVAMDE model - 2.
