Grounding & Lightning Protection

Kumwell deliver safety to society for life and property with an international standard grounding system and lightning protection with perfect standards design for Grounding System, Lightning Protection System, Surge Protection and lightning detection and warning system for safety and security in the infrastructure system in various countries such as electricity sector (Electricity Generation, Solar Power Plant, Wind Power Plant or Transmission, Distribution) Transportation sector (Subway, electric train, high-speed train, airport, port or expressway) Telecommunications sector (Microwave Station, Radio Station, Television Station, Mobile Phone Station or Data Center) Industrial sector (Petrochemical Plant, Oil Refinery, Steel Factory and Farm) Building (Tower, Complex Building, Stadium,
Hospital, School, Home, Castle or Temple)

Grounding

Exothermic Welding Connection

There are several main objectives providing for well designed grounding system: first, Personal safety, followed by equipment protection signal reference quality, return path for faults and surges and static dissipation.

In order to meet these objectives, grounding connection must maintain a low contact resistance often under adverse conditions, for the expected lifetime of the grounding system. Connections in grounding network are subject to severe corrosion, high mechanical stress due to electromagnetic force and rapid thermal heating due to high current magnitude during fault conditions

Graphite Mould

Kumwell Graphite Mould, an exothermic welding mould is made from high quality graphite, accurate production and expert engineering
– Earnest design : captivity, flow path.
– High quality raw material
– Accurate tolerance
– Deration : at least 50 times in normal usage.

Weld Metal Powder

Kumwell Weld Metal Powder is made from high quality material, test and inspection followed international standard UL 467 and IEC
– Non toxic and heavy metal.
– Steady burn without pop and fire out.
– No slag and porosity.
– Consistency of color.
– High conductivity with at least 93% Cu.

Handle Clamp & Handle Clamp Support

Kumwell Handle Clamp is used for handling and clamping the mould fit to the right position and tightening, without leakage during the exothermic welding process.
Kumwell Handle Clamp Support is designed to use with standard handle clamp to increase the capability of usage in all applications such as cable to steel pipe connection, cable to flat surface, etc.

Standard Tools

Kumwell Standard Tools are dedicated to use with the main equipment in exothermic welding connection process.

Flint Igniter	for starting the reaction.
Cable Clean Brush	for cleaning cables and another circular conductor.
Mould Brush	for cleaning mould.
Busbar Brush	for cleaning metal flat surface.
Scraper	for removing slag from mould’s crucible after finishing the connection.

Ground Rod

There are several main objectives providing for well-designed grounding system. First priority is personal safety which followed by protection equipment, signal reference quality, return path for faults and surges, and static dissipation. In order to follow these objectives, all components shall be meet up to international standards as IEC 62561-2, UL 467.
