Power cables and conductors

For power cables and conductors, start with the specific electrical line's requirements. Core count, cross-section and cable designation are different selection elements to consider alongside use conditions.

Compare the full cable designation

The range includes names such as ПВ-А, СВТ, ШВПС, ПВВ-МБ, NYY and NYM. Use them as a starting point for finding the right family. Then check the exact reference and technical documentation. A similar name or identical cross-section is not enough to determine whether two cables can replace each other in a specific project.

Cores, cross-section and length

Record the core count and cross-section required by the specification, distinguishing an individual core's cross-section from the cable's external size. For an individual conductor, also check its construction. If comparing colour markings, check their purpose against the installation diagram. Colour helps identification but does not independently determine product suitability.

Measure the route with the planned connection points and check how the selected item is sold: by length, roll or as a ready-made cable kit. Review the stated installation conditions, insulation and sheath in the documentation. Do not transfer properties between different families solely because they look similar. The electrical circuit must be sized before ordering instead of being derived from the closest commercial offer.

Also plan the circuit ends

Selection continues with connection method. Match the cable to cable ferrules, lugs and connectors where such elements are planned. To join sections, compare cable joints and connectors; for the corresponding connection points, explore terminals and quick connectors. Check permitted conductors for each connecting element separately.

If the task is signal transmission, control or a network connection, go to signal and control cables. For the final comparison, retain a shortlist with the exact designation, cores, cross-section, required length and selected connection elements. This allows offers to be checked against identical criteria and makes differences hidden behind similar titles easier to spot.
