Prysmian flame-barrier cables

Prysmian Power Cables and Systems has developed a range of flame-barrier cables that are suitable for use with non-barrier type flameproof glands and are specifically designed to be used in a variety of hazardous and potentially explosive applications including mine sites, oil and gas platforms, fertiliser plants, chemical installations and explosive manufacturers.

Prysmian’s flameproof cables cover all requirements for LV power, LV control and ELV instrumentation. They offer a substantially compact and circular construction, evaluated and tested for gas groups IIA and IIB to the requirements of AS/NZS 60079.14-2009 clause 10.4.2 (b) and AS/NZS 60079.1-2007 clause 15.2 utilising already certified Exd rated, non-barrier-type flameproof glands with sealing rings.

Armoured cable versions afford wiring protection levels exceeding EPL Gb for non-energy limited wiring systems in accordance with AS/NZS 60079.14-2009 table 6. This protection level is generally adequate for Zone 1 and Zone 2.

There is also an option of specific engineering to provide reduced flame propagation exceeding the requirements of IEC 60332-3 category C bunched vertical test. General market orange circular TPS cables do not necessarily comply with this performance - they are required to comply only with single cable burn test to IEC 60332-1-2, which is not considered adequate performance for bunched cable systems.
