Earth Receptacle

The generation of electrical static charges is a natural

phenomenon. The charge is normally dissipated harmlessly to

ground; however, an arc produced in the presence of flammable

vapours is a hazardous condition. Aircraft must be effectively

and securely grounded prior to performing maintenance, and

when loading/off-loading are being performed.

The earth receptacle must be adequately bonded to a permanent

earthing system. The LECTRO-TECH Earth Receptacle has a

500mm tail that can be ThermexWELDed or clamped to the

earth electrode system.

Manufactured from brass and

HC copper with 70 mm2 copper

anti-theft cable - KWENA & COMPOSITE

EARTHING AND BONDING CONDUCTOR - KWENA

KWENA conductor cable is a composite stranded cable made up of tinned

copper wires and galvanised steel wires that are braided-interwoven to form

the cable.

KWENA can be used as earth bonding cable or jumper bonds where earth

tails are above ground, visible and open to easy theft. The complex braided

and interwoven wires of steel and copper make it very difficult to separate

and is unattractive and uneconomical to copper thieves and scrap dealers.

KWENA is available in "bare" or "insulated" in black or clear.

KWENA has been tested by the SABS and Gerotek Test Facilities for

electrical properties.

Example: 70mm2 copper cable

equivalent KWENA is "70".

Drum length Approximately 290m.

Short lengths available on request

and depending on stock

availability.

EARTHING AND BONDING CONDUCTOR - COMPOSITE

COMPOSITE conductor cable is a composite stranded cable made up of

tinned copper wires and galvanised steel wires that are rope layered to form

the cable.

COMPOSITE applications and benefits are the same as for Kwena.

COMPOSITE is available in "bare" or "insulated" in black or clear.

Denso Paste & Tape

ThermexWELD of KWENA and COMPOSITE

KWENA and COMPOSITE conductors can be welded using

ThermexWELD exothermic copper process for joining of cables.

ThermexWELD can be used for joining both of these cables to Copper

conductors and Steel structures.

The ThermexWELD process generates high temperatures that melt the wires,

resulting in a fused joint. This high temperature will cause some melting of

the tin and galvanising of the wire strands.

To prevent corrosion and or any galvanic reaction in wet or buried Kwena

cable, the joint MUST be properly sealed.

After welding the joint must be Denso Paste/Denso Tape wrapped.

Alternatively a bitumen must be "worked" into the cable strands whilst the

joint is still hot. Protective covering of the surface strands of the cable only

is not sufficient.

E-Mix & E-Mix super conductive

CONDUCTIVE EARTHING COMPOUND (CONCRETE)

Two different compounds are available, both are an easy to use compound

that:

- reduces soil resistivity,

- improves earth electrode contact with soil,

- improves grounding earth resistance,

- traps moisture,

- will not leach out over time.

E-Mix and E-Mix Super Conductive have been tested by independent

authorities.

-E-MIX

Resistivity 1.9 m Conductivity 5.2mS/m Cement included, ready to mix with water.

Size: 25 kg | Bag = 0.03 m3 | Code: E-170

- E-MIX SUPER CONDUCTIVE

Resistivity 0.1 m Conductivity 100mS/m Conforms to EN 50164-7 & IEC 62561-7

Cement included, ready to mix with water.

Size: 25 kg | Bag = 0.03 m3 | Code: E-172

EARTH RESISTANCE

CALCULATOR:Contact us for a copy

of our "E-Mix Earth Resistance

Calculator"

- for single vertical rod

- for trench earth

CALCULATES:

- resistance "with" and "with-out" E-Mix

- number of bags of E-Mix required

USER INSTRUCTIONS

Mix the cement supplied in the bag with the E-Mix compound with water to give a slurry

consistency.

Drilled hole-(70-100mm dia):

Fill hole to approx. 50% of depth

with E-Mix.

Place earth rod in centre of hole.

Fill the rest of the hole with E-Mix.

Agitate rod to remove air-pockets.

Trench-(250-300mm wide):

Add half the depth (25-30mm) of E-

Mix to trench and allow to set so

that earth conductor is supported.

Place earth conductor on top of E-

Mix in trench and add a further 25-

30mm of E-Mix.

Allow E-Mix to semi-harden (24

hours depending on temperature)

before backfilling trench.

Compact backfill 48 hours later.
