Lead free cables

For the first time in Sri Lanka:

The technology field is becoming increasingly advanced in Sri Lanka. Now we do not have to depend on imported techno

 products because Sri Lanka is gaining more progress through researches and utilising expertise knowledge in the techno field.

Moreover Sri Lanka is now preparing to expand its market to the developed countries in Europe, Japan, UK, USA and many more.

Kelani Cables recently launched its latest invention to the market, lead free submersible pump cables and welding cables.

Lead free submersible pump cable

The aim of this product is for safe drinking water because this cable often comes in contact with water. Since lead is poisonous so when it is mixed with water it can be hazardous to human health.

This cable can also be applied in irrigation and industrial projects, mine dewatering, sewage treatment and so on. Submersible pump cables will be able to deliver a lead-free PVC compound with total safety.

The submersible cable is guaranteed by quality assurance at every step. The cable is completely lead-free and is resistant to water, oil and moisture.

Product range

Round cable

The Kelani round submersible pump cable is designed for heavy-duty applications that involve sludge and sewage dewatering pumps. The outer-jacket of the cable is manufactured to withstand abrasion, prevent water ingress while being resistant to chemicals and acids.

Flat Cable

Flat submersible pump cable is particularly designed for submersible pumps in wells. The flat design of the cable helps to overcome physically restrictive and hostile application environments. This cable contains lead-free PVC to ensure safety of drinking water.

Welding cables

Fabricated for hand-held metal arc welding electrodes where high current is generated during secondary connection. It is also used on conveyor systems and on assembly lines in automatically operated line, in machine tools and spot welding machines.

This has a high conductivity, bare annealed copper flexile conductor. Covering consist of two layers with specially developed flexible Elastomer.

Current rating

The maximum current ratings of flexible welding cables for different duly cycles are based on an ambient air temperature of 30 degrees C and a maximum conductor temperature of 90 degrees C. The percentage duty cycles for processes such as automatic welding - up to 100 percent, semi automatic welding 30 percent to 85 percent, manual welding 0 to 60 percent.

Voltage drop

If the cable length exceeds 15m, it is necessary to use cables of larger cross section to ensure that the voltage drop is not excessive and that the welding current is maintained at adequate levels.

This cable can be used in Transformers, Generators, Aircraft service equipment, busbar connections, earthing/return leads, power feeds to electrolytic planting processes.
