Electri-Flex video describes CSA-certified 'heavy-duty' flexible conduit testing

Electri-Flex (Roselle, IL) has announced the release of a new video featuring its line of CSA Certified “Heavy-Duty” flexible conduit, Liquatite Types LA, ZHLA, CBLA, and CSA.

Concurrently, the manufacturer announced that these products have all passed additional testing for tension, cold flexibility, connector compatibility, and crush tests to conform to C22.2 No. 56-17 Annex A “Heavy-Duty” for CSA Certification.

The new video (above) illustrates and discusses the conduit's CSA Heavy-Duty testing and parameters including:

• Tension - Withstands greater tension force: Tested to 500 lbs. which is a 66% greater force applied versus standard CSA and UL testing.
• Cold Flexibility - Superior flexibility in cold temperatures: Placed in a freezer for 4 hours, 300% longer cold exposure, and then wrapped around a smaller mandrel with a 30-37% tighter bend radius.
• Connector Compatibility - Stronger connector attachment: Pulling force of 350 lbs., which is 133% greater force applied versus UL testing.
• Crush - Excellent crush strength: Meets the same tough standards as UL, 1,500 – 2,000 lbs. depending on conduit diameter.
