Cables and wires

Twisted pair is one of the components of modern structured cabling systems. It is used in telecommunications and in computer networks as a physical medium for transmitting a signal.

Details

The cable is designed for laying by hand and mechanized methods in soils of all categories with low, medium and high corrosivity, including those infected by rodents, except those prone to frost deformation. Laying in cable ducts, pipes, blocks, manifolds, etc. is also possible. with the danger of damage by rodents.

Details

The cable is designed to operate at voltages up to 380 V and frequencies up to 10 kHz on subscriber telephone lines and distribution networks. Laying in the ground, telephone sewage, collectors, on the outer walls of buildings. Allowed laying on poles overhead lines in areas not exposed to strong winds and icy conditions.

Details

The cable is used to connect a surveillance camera with a video recording device - a DVR or video capture card, and it also serves to supply power to the camera. The signal from the camera is transmitted via cable to the recorder, where it is further processed.

Details

The cable is designed for suspension and operation on supports of overhead communication lines, urban electric transport and overhead power lines under the influence of loads from wind, ice, temperature, and their combinations. When the electric potential at the point of suspension is more than 12 kV, tracking resistant polyethylene is applied to the shells.

Details

The cable is designed for electrical communications and railway alarm systems, centralization, interlocking and automation with a nominal alternating voltage of 380 V or a direct voltage of 700 V. Laying in the ground (in trenches) in a hostile environment in the absence of mechanical effects on the cable.

Details

It is used for space heating (for floor heating) at low mechanical cable loads (class M1). The operating temperature of the cable, not more than 65 ° C. Specific power, max. 15 W / m.

Details

Three-core power cables with copper or aluminum conductors, with insulation made of cross-linked polyethylene, armored with galvanized steel tape, in an outer sheath of PVC plastic. Cables are intended for transmission and distribution of electric energy in stationary installations.
