ACDC Dynamics, sole distributor of the Gewiss
product range in South Africa, recently launched
a new range of IEC309 High Performance plugs
and sockets.
“The newGewiss IEC 309 High Performance
range is a high-end range of industrial connec-
tions, which deliver outstanding performance,
functionality and technical features,”says ACDC
Dynamics’brandmanager, ChrisWatt.
“The range includes a comprehensive assort-
ment of products to create any kind of service or
industrial systemand is designed tomake installa-
tions simpler andmore efficient,”he says.
New, innovative design for plugs and sockets
used in trailing systems.
Raised earth terminal:
The new IEC309 High
Protection range features a raised earth termi-
nal and, in the event of a connection cable be-
ing accidentally pulled out, the earth cable will
be the last to be released, preventing the user
from sustaining an electric shock and avoiding
electrical discharge on devices.
New cable clamping system:
The new ex-
ternal cable clamp on all versions secures the
cable andmaintains the IP rating. It can easily
be closed by handwithout the use of tools
while the anti-loosening device prevents the
accidental unscrewing or loosening of screws –
even when subjected to considerable vibration
or mechanical stress. The cable gland accom-
modates a range of cables above regulatory
requirements.
Nickel-plated pins and contacts:
All IEC309
High Performance range products feature
nickel-plated pins and contacts for more effi-
cient contact on elements with a higher degree
of oxidisation. The nickel-plating guarantees
maximumproduct life and allows for use in en-
vironments with critical climatic conditions (ma-
rine environments) or aggressive substances.
Single pack:
Each IEC 309 HP range item is
individually blister-packed, which ensures that
the product remains clean in storage.
Halogen-free:
All products aremanufactured
using halogen-free technopolymer and con-
form to EN50267-2-2.

The new range expands the Gewiss assortment
of 16A and 32Amobile plugs andmobile and
flush-mounting socket-outlets giving IP44 and
IP66, IP67, IP68 and IP69 protection in the quick
and screwwiring versions.
“The range can be wired and assembled
quickly and simply, which is a unique feature in
themarket,”saysWatt, adding that the range has
also been restyled as a single, modern, functional
line.
“The range includes 63A and 125A plugs and
socket-outs with polarity, voltage and nominal
frequencies suitable for all systems up to 500V,
andwith IP44 protection and IP67 watertight
versions, multipliers and adapters, low voltage
versions, as well as 90°, straight flush-mounting
and 10° surface-mounting versions.
He explains that themain features of the IEC
309 High Performance range are:
Safe lock closure:
The ¼ turn screw guarantees
practical, simple use with quick assembly and safe
closing due to the readily identifiable reference
system. In addition, the same screwdriver for
conventional wiring can be used. Manufactured
from reinforced technopolymer, the safe-lock
systemensures maximum resistance to abrasion,
which ensures a long lifespan and eliminates the
problemof themetal closing systembecoming
corroded, even in aggressive environments such
as water and steam.
Practical and ergonomic:
All mobile socket-
outlet covers are designedwith a special shape,
whichmakes them safe and easy to open – even
with one hand.
New functional coupling system:
The units
feature a nibbed screw – a product requirement
for secure socket-outlet covers. The innovative
shape of these newproducts enables them to be
coupled to fencing and scaffolding when being
ABERDARE Cables, amember of the Powertech
Group, a leadingmanufacturer of cables and distribu-
tor of related electrical accessories supplies earth
continuity conductor (ECC) cable.
An ECCmaintains the continuity of the earthing
(grounding) circuit throughout an electrical system.
It could be a bare conductor or single core cable or
one-core of amulti-core cable. Generally, the size of
the grounding conductor is smaller than the power
conductor in amulti-core cable.
An ECC cable is a bells or mains cablewherein some
of the steel armour wires are substitutedwith tinned
copper wires.This cable is identified by a brown stripe
on the sheath.
Copper has less resistance and better conductivity
than steel so the effect of the tinned copper wires
means that ECC cable has a higher earth fault
capacity when using the armour as an earth return
path.
Additionally, the tinning of the copper also provides
corrosion resistance, andmakes these copper wires
look almost identical to the steel wires.This does
not mean that a separate earth is no longer neces-
sary. Although the armour wires of bells andmains
cables can be connected as an earth, it is always good
practice to have a separate earth (bare/insulated) to
connect the earth circuit.
SANS 10142-1 even specifies that a separate earth
and neutral be run to each appliance beyond the
point of supply. In this way, if the separate earth gets
stolen for instance, then at least there is still an earth
return path on the systemuntil the stolen/damaged
earth is replaced and vice versa.
