- Cables are used in industrial installations and distribution devices, connecting houses and street lighting to electrical networks. Cables are intended for laying in the open air, in the ground, indoors, in cable channels. The concentric wire can be used as a grounding wire (PE), neutral wire (PEN) or as a screen.
operation: from -60°С to +50°С

Power cables with aluminum conductors, insulated and sheathed with polyvinyl chloride (PVC), featuring a concentric conductor for electrical current transmission. These cables are designed for the transmission and distribution of electrical energy in stationary electrical installations at a nominal voltage of 0.6/1 kV, where enhanced electrical and mechanical protection is required.
Conductive wires – aluminum, single-wire or multi-wire (class 1, 2 DSTU EN 60228).
Cables are intended for operation in a stationary state at an ambient temperature of minus 40 to plus 50 °C, relative air humidity up to 98% at a temperature of up to 35 °C, including for laying in the open air.
Cables can be laid without preheating at a temperature not lower than minus 5 °C.
The minimum bending radius during installation must be at least 15 times the outer diameter of a single-core cable and 12 times the outer diameter of a multi-core cable.
The long-term permissible heating temperature of cable cores during operation is 70 °C and the maximum permissible temperature for short-circuit currents is 160 °C (for cables with current-conducting cores with a cross-section of up to 300 mm2 inclusive) and 140 °C (for cables with current-conducting cores with a cross-section of more than 300 mm2).
