Frequently Asked Questions (FAQ)
Which extension cable is best for continuous use on construction sites?
H07RN-F rubber cables with 3x2.5 mm² cross-section and IP44 rating. They are extremely abrasion-resistant and withstand mechanical stress and weather exposure over long periods.
Can extension cables be permanently installed outdoors?
Yes. Our IP44 and IP67 protected rubber cables are specifically designed for outdoor use. Proper installation without kinks and regular visual inspections are recommended.
How do I calculate the maximum load of an extension cable?
For 3x1.5 mm² approx. 3,500 Watts (16A). For 3x2.5 mm² significantly higher loads are possible. Always consider the total power of connected devices and voltage drop on longer runs.
Are these cables suitable for van conversions?
Yes. Their high flexibility and robustness make them an excellent choice for mobile power solutions in vans, campers, and commercial vehicles.
What are the advantages of H07RN-F over standard PVC cables?
H07RN-F offers superior mechanical strength, better resistance to cold and oil, and significantly longer service life under tough working conditions.
Do you offer custom lengths or special configurations?
Yes. We manufacture custom extension cables according to your specifications — perfect for businesses and large-scale projects.
What is the best way to store extension cables?
Store them in loose loops or on proper cable reels. Avoid tight coiling for long periods to prevent material fatigue.
