Cables for the Power Engineering and Automation Sector

The power engineering industry, as a key sector of the economy, requires the highest standards of reliability for infrastructure components. Selecting the appropriate cabling for power transmission, control systems, and safety installations must take into account the specific working environment, mechanical hazards, and strict fire protection requirements.

Power Supply and Control Systems – YKY and YKSY Standards

In fixed installations, both inside and outside buildings, the basic solution consists of cables with PVC insulation and sheath designed for a rated voltage of 0.6/1 kV.

YKY cables:
Designed for electric power transmission, constructed with solid copper conductors with cross-sections ranging from 1 to 300 mm². For cross-sections above 10–16 mm², stranded conductors (RM) are used.

YKSY cables:
Dedicated to control, protection, and automation systems. They are characterized by a large number of cores (from 2 to 61), enabling the implementation of complex automation schemes.

Protection Against Mechanical Hazards – Armoured Cables

In locations where cable routes are exposed to mechanical damage (pressure, impacts, excavation works), reinforced cable constructions must be used. The armour protects the cable core from insulation failure and short circuits.

Steel tape armour (types YKYFtly, YKSYFtly):
Provides an effective barrier against mechanical compression.

Steel wire armour (types YKYFoy, YKSYFoy):
Recommended in environments requiring higher tensile strength and improved point-impact resistance.
