LSZH (Low Smoke Zero Halogen) High Performance outer jacket

Complete cable assembly exceeds IEC61034-1:2005, IEC 61034-2:2005 IEC60332-1-2:2004, IEC 60754-2:1991 for fire and gas emissions.

Dual screen of conductive foil and woven braid for excellent noise rejection

True 75 Ohm characteristic impedance

Low loss foamed polyethylene dielectric

Most cables feature PVC insulation, some have a basic fire rating such as CL3, etc. Unfortunately, most cables give off hazardous toxic smoke during a fire, posing a very serious health risk.

LSZH cables are made from a special compound that performs as well as PVC insulation, but crucially gives off very little smoke and no halogen toxins in the event of a fire.
Many leading architects and builders along with commercial and marine designers are now specifying LSZH spec cables as standard.

Only LSZH cables meet the legislated fire specifications for boat installations.

Each complete QED Professional cable design is fully tested to LSZH standards and reports are available on request.
We don't just use a fire rated jacket material over an ordinary cable assembly; each complete cable design including jacket and all internal conductors has to undergo rigorous fire safety testing to the following standards:

IEC 61034-1:2005
IEC 61034-2:2005
Measurement of smoke density of cables burning
under defined conditions.

IEC 60332-1:2004
Test for vertical flame propagation for a single insulated wire or cable.

IEC 60754-2:1991
(Amendment1, 1997) test on gas evolved during combustion of electric cables.
