Anti-Static Applications
Clause 7.4 of EN60079-0 refers to the avoidance of a
build-up of electrostatic charge on Group I or Group II
electrical equipment. Electrical equipment shall be so
designed that under normal conditions of use,
maintenance and cleaning, danger of ignition due to
electrostatic charges shall be avoided. This
requirement is satisfied by suitable selection of the
material so that surface resistance complies with either
of the limits given below when
measured in accordance with 26.13;
10
9
Ω
measured at (50 ± 5) %
relative humidity; or 10"
Ω
measured
at (30 ± 5) % relative humidity.
Flexicon have two ranges of anti-
static performance coated liquid
tight systems.

Why Use Conduit Over Cable?
In summary, using a Flexicon conduit system with our EXD barrier glands or EXE fittings can provide the following benefits over cable:
•
Simplified termination and
greater enclosure integrity
•
Reduced installation time
- less terminations
•
Cable is mechanically
protected
KG
•
No need for
specialist cables
£'s
•
Flameproof integrity
with EXD glands
•
Can provide EMC screening
(braided versions)
•
No need for use
of SWA cables
