The Benefits of Using BS Standard Cable 

BS cable features Electric cables &#;The thermosetting insulated and thermoplastic sheathed cables for voltages up to and including 450/750 V for electric power and lighting and having low emission of smoke and corrosive gases when affected by the fire.

This British Standard specifies requirements and test methods for the construction and performance of cables that:

a) have thermosetting insulation of rated voltage up to and including 450/750 V;

b) Emit limited amounts of smoke (see 16.6) and corrosive gases when subjected to relevant tests compared with corresponding PVC cables conforming to BS ;

c) are intended for electric power and lighting. 

The types of BS cable included are:

&#; thermosetting insulated and thermoplastic low smoke halogen-free sheathed cable 450/750 V single core B; 

&#; thermosetting insulated and thermoplastic low smoke halogen-free sheathed circular cables 450/750 V, 2-core B, 3-core B, 4-core B and 5-core B ;

&#; thermosetting insulated and thermoplastic low smoke halogen-free sheathed cables 300/500 V single-core B, flat-twin B, flat 3-coreB with circuit protective conductor.

The insulation and other components are suitable to permit operation of the cables at a maximum sustained conductor temperature of 90 °C and for a maximum short-circuit conductor temperature of 250 °C (for a maximum period of 5s)

Bs EN -3-41 applies to cables with special fire performance -- non-sheathed single-core cables insulated with halogen-free crosslinked compound and having low emission or smoke and corrosive gases when exposed to fire.

The cables are of rated voltage u0/u up to and including 450/750V. The cables are intended for fixed wiring applications. The maximum conductor operating temperature for each of the cables in this standard is 70&#;.

The cables include the following items:

1) cables for fixed wiring H07Z1-U and H07Z1-R

2) cables for fixed wiring &#;h07Z1-K

3) cables for internal wiring-h05Z1-U

4) cables for internal wiring-h05Z1-K
