We are offering Speed Control Resistor to our clients. For starting/Speed Control of AC or DC Motors, resistors are manufactured as per customers requirement at specified starting torque or for limiting initial inrush current to an acceptable value. Mainly these are used for cranes. The rating can be 2 minutes, 5 minutes, 10 minutes, continuous or intermittent. The material of resistor is normally Stainless steel AISI-304, AISI -410 or AISI 430 or FeCrAl-AISI-406.

Standards Followed:
  • IPSS-1-10-002-82 with amendment no.1 and BS 587 for starting/speed control resistor
  • IS 2147 & IS 12063 of 1987 for the degree of protection for an enclosure
  • IS 5 for paint shade
  • Any other standard as required can also be followed

Routine Tests: Following tests Will Be Conducted

Visual and Dimensional:
  • Insulation resistance value measurement by using 500V megger before and after the dielectric test
  • Resistance value measurement with ± 10 % tolerance
  • H.V. Test of twice the rated voltage +1000 volts for voltage class below 660 volts

Type Tests: Temperature rise test i.e., Heat run test, if required, will be conducted by passing equivalent/rated current for rated/equivalent time keeping IT Constant through a part of Resistor.
