KVVG cable description

KVVG is TCG's main control cable for control, signalling and automation systems in switchgear. Solid copper conductors (4-37 cores in increments per GOST) provide a reliable connection between terminal blocks and equipment contacts. Cross-sections of 0.75-10 mm² suit most control circuits and signal lines.

It is used in control cabinets, at distribution points, and for connecting sensors and actuators in automated control systems. It is not intended for installation in the ground without protection – for that, choose KVBbShv (armoured), or KVVGng(A)-LS for fire-hazard areas.

Applications

Control and signalling circuits of electrical installations

Switchgear up to 660 V

Automation (automated control systems) and supervisory control systems

Links between control cabinets and actuators

Fixed installation indoors and in cable structures
