KSHVEmBSHv

1. Main electric conductor – copper multiwire, round or sectoral shape acc. to grade 2 GOST 22483. Additional, ground conductor - copper multiwire, round shape acc. to grade 5 GOST 22483. 

2. Insulation – from PVC compound. Insulation colour of the main conductors – natural, brown, black. Additional conductors have any colouring, except for black and distinct from main conductors colouring. Ground conductor applied without insulation. 

3. Electric conductive shield – from conductive non-woven fabric, winded on main conductor 

4. Metal shield – from copper bands. 

5. Core conductor – shielded, main insulated conductors, additional and ground conductors twisted between each other. Main cable conductors with round shape, inner and outer spaces between conductors filled with harnesses from PVC compound. Main cable conductors with sectoral shape, inner space between conductors filled with harness from PVC compound. 

6. Separating layer – PVC film (for cable with main round shape conductor). 

7. Inner sheath – from PVC compound, laid with filling of inner spaces between conductors to make the cable round shape. 

8. Armour from two steel galvanized bands. 

9. Outer sheath – from PVC compound, coloured in yellow for cable voltage 0,66kV, blue colour for cable voltage 1,2 kV, red colour for cable voltage 6 kV.

For cable KSHVEmBSHvng(A) – inner and outer sheath from low fire performance PVC compound.

For cable KSHVEmBSHvng(A)-LS - inner and outer sheath insulation from low fire hazard PVC compound. 

For cable KSHVEmBSHvng(A)-XL - inner and outer sheath insulation from low fire performance PVC compound with low glass transition temperature. 

Mine power cables with copper conductors, insulation and sheath from PVC compound, armoured, KSHVEmBSHv, KSHVEmBSHvng(A), KSHVEmBSHvng(A)-LS, KSHVEmBSHv-XL used for transmission and distribution of electric energy in mine electric networks at horizontal and inclined mine working laying without limitation of level differences on the surfaces of mines, ore mines and wells for suspension to the rope at nominal voltage of main conductors 0,66; 1,2; and 6 kV and nominal alternating voltage of additional conductor 0,38 kV, nominal frequency 50 Hz. 

Maximum network voltage for cable operation – 7,2 kV alternating current. 

Cables must not object to crushing and impact loads. 

Cables should have sealing ends of main conductors. Armouring on the cable ends should be banded. Cable must not be used with damaged outer layer. During cable operation ground conductor should be connected to the ground terminal. 

Displacement of voltage-carrying cables manually strongly prohibited. Transporting of voltagecarrying cables applies with dielectric rubber gloves and footwear or clamp with dielectric handle by operators. Drum must not be laid flatwise as well as cable winding through the drum flange. 

Additional conductor must be connected to the integrity control equipment of ground conductor, which provides alarm and automatic shut-off of the cable line during cable operation. 

It`s necessary to make ground conductor integrity check under operation without additional conductor. Cables must not be used in case of ground and additional conductor malfunction
