Cable Design

A Submersible Pump Cable is a specialized product to be used for submersible pump in a deep well. The area of installation is physically restrictive, and the environment is very hostile. Rialto is designed and manufacured keeping in mind these factors to achieve the highest possible degree of reliability.

 

Application

  • Designed for the secondary (high current) connection to automatic or hand – held metal arc welding electrodes
  • Suitable for flexible use under rugged conditions, on assembly lines and conveyor systems, in machine tool and automatically operated line and spot welding machines
  • Standard length cable packing:
    Coils 100, 200,300 and 500 m. in wooden reels
 

Features

  • Ultra high performance flexible welding lead, double insulated
  • Better flame retardant properties
  • Excellent flexibility to last longer in flex applications Based onCENELEC HD 22-6 31, VDE 0282, IEC 245-6, IS 473, BS 638-4
  • Outstanding toughness & durability
  • High resistance to cuts, tears & abrasion
  • Resistance to oil, solvents and chemicals
  • Excellent ozone and weather resistant.
 

Voltage Drop

When total cable lengths in excess of 15 mtrs., are involved , it may be necessary to use cables of larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.

Current Rating

The maximum current ratings of flexible welding cables for different duly cycles are based on an ambient air temperature of25°C and a maximum conductor temperature of 90°C. The percentage duly cycles for various processes and applications are as follows:

  • Automobile Welding : Up to 100%
  • Semi-automatic welding : 30% to 85%
  • Manual Welding : 0% to 60%
  • Very intermittent or Occasional Welding : Up to 20%

CE =The Product is confirmed with the EC to the Low Voltage Directive 73/23/EEC
