www.arcolresistors.com About Us

power resistor solutionsavailable anywhere. Carefulselection of the winding wiresfor both stability and pulsecapability is combined withadvanced winding skills ontohigh purity alumina cores.Encapsulation utilising latestinsulating materials signifi-cantly improves dielectricbreakdown voltages.

More than standard resistors,Arcol also delivers completeresistive solutions, requiringonly the basic circuitperformance and the realestate available to be defined.

“At Arcol we have accumulated experience in allaspects of design, production and application ofresistive solutions, and are dedicated toproviding you the most complete customisedservice available anywhere.

At our headquarters, we maintain a flexibleapproach in terms of both design and theallocation of resource.

By consulting us early in your design process,we will, where possible, modify a standardproduct or process to meet your need at aminimum cost. If appropriate, we are competentand prepared to develop an entirely newsolution, drawing on different technologies toensure the best-fit solution.

We routinely then provide a prototype with littlefuss or delay – normally free of charge.

We supply custom-designed resistive product toautomotive, military aerospace, instrumentation,power transmission, traction and wind energy …for use in both benign and extremely hostileworking environments.

Our manufacturing and test systems areapproved to ISO 9001.

We can generate a specification and thenundertake type approval, to include functional,parametric and environmental testing.

This is what we call customer service!”

Arcol - The Problem Solver

When faced with a unique challenge of convertingconventional motorcycle filaments to high intensityLED’s, ARCOL were able to develop a compactresistor kit that enables the user to select andinstall a ballast specific to the vehicle lightingrequirements.

Consistently in the front line of new applicationstechnology, Arcol works closely with the leadingdevelopers of control electronics for wind energy turbines.

Frequent fluctuations in wind speed and intensitypresent Arcol designers with a challenge insupporting the generation of smooth andconsistent system power download.
