NYCY is a power cable with copper conductors, PVC insulation and sheath, shielded. It is designed for the transmission and distribution of the electricity in stationary electrical installations for a rated alternating voltage of 0.66 and 1 kV with a frequency of 50 Hz.<\/p>\n
NYCY is one of the most durable, highly reliable and resistant to mechanical deformation type of power cables. Its feature is a shield that prevents the propagation of interference-carrying electric and magnetic fields. The cable is used for indoor and outdoor wiring, installation in household and industrial premises, various devices and machines, for laying in wiring ducts and in the open air in conditions that exclude the impact of mechanical damage and significant tension strain. In case of single laying, the cable is flame-retardant.<\/p>\n
At the same time, there are varieties of VVGE made of non-combustible materials. Such cables are marked with indices \u00abng\u00bb and \u00abngd\u00bb. Due to the special sheath production technology, VVGEng and VVGEngd cables are flame-retardant and used in places with a high risk of fire.
According to the design, it is a cable with round copper conductors of the 1st or 2d flexibility class (class 1, 2 DSTU EN 60288), with number ranging from 1 to 5. The insulation of the conductors and the outer sheath are made of PVC compound. And the shield can be made of aluminum foil or in the form of copper wires fastened with copper band. In multi-conductor cables, the conductors are stranded, and their insulation is color-coded or numerically coded.\u00a0<\/strong><\/p>\n The operation of NYCY is allowed in a stationary state at temperatures from -50\u00b0C to +50\u00b0C and relative air humidity up to 98% at a temperature not exceeding +35\u00b0C. The installation without preheating of the cable is possible at a temperature not below -15\u00b0C.<\/p>\n The permissible bend radius during installation for a single-conductor cable is not more than 10 external cable diameters, for a multi-conductor cable – 7.5 diameters. The allowable tension strain of cables along the route of laying should not exceed 50 N\/mm2<\/sup> of the conductor cross-section.<\/p>\n The long-term permissible heating temperature of cable conductors during operation is 70\u00b0C, the maximum permissible temperature at short-circuit currents is 160\u00b0C, and in an emergency mode – no more than 80\u00b0C.<\/p>\n Cables serve for at least 30 years. The guarantee service life is 5 years.<\/p>\nOperation<\/strong><\/h5>\n
