Application

Insulated conductor is used for laying in electric-installation tubes, under and on plaster installation in dry rooms and in closed installation conduits. Direct laying in cable guides is not permitted. Also applied for internal wiring of distribution and switching boxes equipment, same as for protective laying for lighting of nominal voltage up to 1000 V alternating current, or up to 750 V direct current against earth.

Construction

Conductor:		bare copper conductor of class 1 (solid) acc, to IEC 60228 / HD 383 / DIN VDE 0295
Insulation:		PVC compound TI1 acc. to IEC 60227-3 / HD 21.3 S3 / DIN VDE 00281 part 3
Conductor colour identification:		acc. to IEC 60446 i.e. EN 60446 (corresponding to DIN VDE 0293)
possible insulation colours:
– yellow-green color is used only for protecting conductor, and green and yellow ones are permitted only if allowed by security regulations, i.e. if they can not get mixed up with the yellow-green conductor
– blue color is used for neutral conductor, black and brown are applied for alternating current phase conductors
