Application

The wire and the cable may be used for inner and outer connections of rolling stock of rail transport and trolley-buses, assembly in case of restricted transportations, connection to rolling trolleys and fixed assembly, under the influence of lubricating oils and diesel oil (, ); and for connection to rolling trolleys (-1).

 

Construction

Cable leads
Round copper multi-wired stranded (class 4 according to GOST 22483-77).

Insulation
PVC.

Wrapping
PVC.

Wires and cable stand alternate voltage testing at 50 Hz during 15 minutes upon 24 hours in water as shown in the table 1.

Reheat temperature permitted for a long period is 70C.

Do not conduct burning when laid separately.

Wires and cables are bend- resistant. Cables and wires for connection to rolling trolleys are resistant to bends with simultaneous twisting.

Electric insulation resistance evaluated in 1 km length and temperature of 20C, at least 6 MOhm.

Wires and cables are oil proof.

Wires and cables resist to vertical oscillation of 1 up to 3 Hz at acceleration amplitude of sinusoidal vibrations, determined by m/s², which is numerically equal to frequency Hz.

Wires and cables resist vibrations of 3 up to 100 Hz at acceleration of sinusoidal vibrations of up to 150 m/s² and hits at acceleration of up to 150 m/s².

Construction length — at least 100 m.

The cable shall be installed at the temperature not lower than -15C, while bending radius shall be at least three cable or wire diameter.

In absence of hits cables may be connected with power on and off to trolleys at a smooth bend with a radius equal to five cable or wire diameters at — 50C.

Warranty assurance — 2 years from the date of putting into operation.

Manufacturer certifies quality compliance to the present standard requirements provided the terms of operation, storage and installation are observed.

Durability of cables and wires for connection to rolling trolleys constitutes at least 6 years, and ro fixed ones — 12 years.
