Before
introducing Exothermic Welding System, firstly you have to be aware
about Exothermic welding process. This process is basically a welding
process of joining materials that employs molten metal to permanently
join the conductors. The process use an exothermic reaction of a
thermite composition to heat the metal, and requires no external
source of heat or current. It is very efficient method of making high
quality electrical connections. Moreover, it is used to create
electrical molecular bond between different metals such as cooper to
cooper, aluminum to copper etc.
This
Exothermic Welding System is very cost effective and efficient method
of making large number of high quality electrical connections.
Moreover, it is a self contained system that utilizes high
temperature reaction of aluminum, copper oxide within a mould form.
This system contains Graphite mold, Metal disc, Fastening clamp,
powder, Steel brush, Banister brush, etc. Exothermic Welding Powder
is included in the Exothermic Welding Kit.
When
it is used:
Exothermic
Welding Equipment is most commonly used for permanently joining
copper conductors. It is the only acceptable means of bonding copper
to:
- Stainless Steel
- Copperweld
- Nichrome V
- Galvanized Steel
- Silicon Bronze
- Copper Clad Steel
- Columbium
- Plain Steel
- Everdur
- Kama
- Steel Rail
- Cor-Ten
Exothermic
Welding Graphite Moulds or simply Exothermic Welding Moulds are
available to suit your application. Its particular application
includes:
- Cathodic protection
- Earthing for power plants & substations
- Rail connections
- Telecommunications
- Transmission & power distribution lines
- Residential Power Systems Grounding
Its
good electrical conductivity and high constancy in the face of
short-circuit pulses is commendable, therefore its one of the option
mentioned by United States National Electrical Code for grounding
conductors and bonding jumpers. Furthermore, this system has been
shown to be the ideal choice where safety, dependability, longevity
and current carrying capacity are critical.
The
first thing I want to say about this system is its higher mechanical
strength and its stability when subject to repeated short-circuit
pulses. It’ s also not suffer from increased electrical resistance
over the lifetime of the installation. This system produce a
permanent connection, excellent in performance to any known
mechanical or pressure type surface-to-surface contact connector.
Features:
- Excellent electrical conductivity to the conductors themselves.
- Does not oxidize, corrode or degrade with time and is resistant to galvanic coupling.
- Able to withstand repeated electrical discharges.
- Never increases its resistance.
- It assure the most common connections not only between copper cables but also for metallic pieces and welding tapes made of stainless steel, brass, and copper coated steel earth rods.
- Has greater mechanical and squeezing resistance than the conductors themselves.
