Eland Cables Cable By Standard3

BS7917 Cable

Elastomer insulated fire resistant (limited circuit integrity) cables for fixed wiring in ships and on mobile and fixed offshore units manufactured according to British Standard BS7917.

BS7917 Standard Cable

British Standard BS7917 covers a wide range of cable types used in fixed wiring applications on ships and offshore units and complements BS6883, which also covers marine cables used for fixed wiring of lighting, power, control, instrumentation and propulsion circuits in ships and other offshore units up to and including 3.3kV without fire resistant circuit integrity. It sets out the constructional requirements and additional tests under fire conditions.

The purpose of producing BS7917 was to promote the use of cables with fire resistance in the event of fire.

BS7917 cable designation

As per BS6883, cables manufactured in accordance with BS7917 are designated according to their outersheath type.

BS6883 Type SW2 Heavy-duty enhanced oil-resisting, flame retardant, with reduced halogen gas emission
BS6883 Type SW3 Ordinary duty oil-resisting with low emission of smoke and corrosive gases when affected by fire
BS6883 Type SW4 Ordinary duty enhanced oil-resisting with low emission of smoke and gases when affected by fire
BS7917 also specifies the following fire resistance performance characteristics:

F0 Fire resistance for 3h at 750oC
F1 Fire resistance for 3h at 950oC

BS7917 cable construction

The construction of these cables follows the specifications set out in BS6883. In addition, BS7917 specifies the use of tape or tapes over the conductor or over the insulation in order for the cable to meet the relevant fire performance requirements.
