Exothermic Weld Materials

Exothermic Welding process is a very efficient method of making high quality electrical connections and welding is used to create molecular bonds for various metals such as copper to copper, copper to steel, steel to steel, aluminum to copper and aluminum to aluminum. No external source of power is required for the welding.

Exothermic welded connections use high temperature of reaction of powered copper oxide and aluminum. The reaction takes place in a semi-permanent graphite mould that lasts for fifty or more welds if properly cared for.

The exothermic welding reaction takes place in a very few seconds, therefore the total amount of heat applied to the conductors or surfaces is considerably less than that employed in brazing or soldering. Tools of exothermic welding are very light in weight. So it saves time and the occupation or pay of a worker than others.

Different types of don conductors are used such as 25*3mm Cu tape or 25*3mm GI tape or 600V graede-50sq.mm, PVC insulated cable. Copper tape, 25*3 mm.Copper cable, 600V grade, 50 sq.mm, PVC insulated cableGI tape, 25*3mm.

The compound consists of a chemical solution of good electrical conductivity, which, when mixed with water and poured onto the earthing grid and surrounding soil, becomes a gelatinous mass which forms and integral part of the earthing system. The great advantage of the compound is that it will not wash away like most other earth improving mixtures. This reduces the requirement for redosing of the earth grid as is the case with most other earthing additives.

Various types of Moulds are available to suit to the shape and size of the conductors to be joined with exothermic weld. We can prepare the mould for any new type of the joint.

The Sectionalisers are normal Load break switches with built-in capability to open automatically. The Sectionalizers are designed to open based on the fault count setting. The Sectionaliser trips in no-load condition, after Auto Recloser has opened and before it recloses again.

FTU is a kind of IED (Intelligent Electronic Device) for power system automation, which is a fully digitalized and microprocessor-based control device, and through connecting with this control device, Recloser can play a role of automated protection device.

The weld metal is available in measured quantities in packs, suitable for particular type of joint. The conventional pack contains the exact quantity of loose material in the pack which must be poured into the mould and to be ignited using the conventional flint igniter. to make the joint. The other type of the pack is capsule type where the material is sealed in a capsule and is ignited by passing the current using the special igniter.

• LSC works with an inductive effect of the lightning strike current. The events are monitored by a mechanical counter display
• LSC is a serial counter with 6digit mechanical display unit
• It detect the lightning currents, which is more than 2KA
• LSC does not require any external power supply
• The lightning event counter shall be installed to the manufacturers instructions in a readily accessible manner so that readings can be taken at regular intervals. It shall be positioned such that its operating temperature is in the range of 10 deg C to +50 deg C
• The lightning event counter shall be robust, easy to install and housed in an IP67 rated enclosure. The counter shall operate from the energy of the lightning discharge and not rely on external or battery power to operate

The Auto Reclosers are the Circuit Breakers with built-in automatic Reclosing and Opening capability (Auto Reclosing) under fault conditions. The auto reclosing functions are limited to preset number of times at preset intervals after which, it gets locked out. The auto reclosing feature is useful in avoiding the permanent shutdown in case of temporary faults.

The Power line Surge Protection Devices (SPDs) are classified based on the location where it is installed (at the point-of-entry or at the point-of use) or needed and the connection (series or parallel). Several intelligent features are incorporated in the design of these SPDs to ensure that the SPD will function only in case of line surges rather than the nominal voltage fluctuations, thus enhancing the life and reliability of SPD.
