Why Kalas GenFlex™ Type W is the Power Cable You Want

Whether you are powering generators for disaster relief, equipment for mining, large outdoor productions, active facilities, or other high-stakes situations that require consistent reliable power, there’s a lot on the line if your power fails. Your power cables and systems need to be able to withstand environmental factors and extreme use. Before selecting the type or brand of cable you choose to power your end-use, you need to find a cable you can trust with all you put it through.

That’s where Kalas GenFlex™ Type W Power Cable comes in. Let us explain why we believe our Type W Cable is the brand you want when making your selection for purchase.

What is Type W Power Cable?

Before we get too deep into why you would choose Kalas’ Type W Power Cable over the rest, we don’t want to assume you know the ins and outs of Type W Power Cable. Type W Power Cable is basically a heavy-duty cable. What makes it different than other Industrial Power Cables and Cords is its ability to power extreme uses. Type W Power Cable generally consists of bare copper conductor core insulated with Ethylene Propylene (EP) and jacketed with Chlorinated Polyethylene (CPE) which results in a cable that is flexible, durable and can maintain it’s properties in extreme temps, weather and compression. Perhaps this isn’t new information and you already are familiar with Type W Power Cable and what it’s generally used for. If that’s the case, all we need to share is why would you choose Kalas’ GenFlex™ Type W Power Cable before it’s the competition? We’re glad you asked.

Why Choose Kalas GenFlex™ Type W Power Cable?

When it comes to Kalas’ Type W Power Cable, we give you not only the basics of reliable construction but peace of mind as you can trust you’re receiving a quality that outlasts the competition.

Complete Quality Control

First, we make every one of our wires & cables from scratch in-house. That means from the very start we get to control the quality of your cable and can vouch for each inch of it. We order our own copper rod and draw it to the precise stranding your cable requires all while assuring it to be defect-free and as conductive as possible. Next we go through extensive quality testing before selecting insulation and jacketing suppliers to assure our customers will receive a product that lives up to and exceeds expectations with which it’s purchased.

Tested and Proven for Durability

Before rolling out any product, we put it through extreme testing. Our GenFlex™ Type W Power Cable has been tested and proven to meet the requirements of UL Subject 1650; CSA PPC 22.2 – 96 and the MSHA Flame Test. It’s tested and proven to be rated for use in accordance with National Electrical Code (NEC) article 400 and NFPA 70 such as used in generator leads, battery leads or motor leads, heavy-duty, or temporary power supplies and light to medium duty mining applications. When you buy Kalas’ GenFlex™ Type W Power Cable, you also buy assurance that your cable will hold up to and resist abrasion, sunlight, chemicals, oil, and water offering you superior cable life in the harshest environments. Because of the quality of our Type W cable, it’s also rated to temperatures of -40°C (-40°F) to 90°C (194°F wet or dry), so even in extreme temperatures, you’ll be able to rely on our Type W remaining consistent and flexible to move with ease without compromising conductivity.
