Frequently asked Questions
Which UL approvals are available for cables?
In America, the UL (Underwriters Laboratories) testing institute is a major institution for testing and approving electrical systems. The relevant approvals can apply to entire systems as well as individual components.
UL categorises cables into the UL recognized approval in compliance with the 758 standard "Appliance Wiring Material" (AWM) and various listings. AWM (Appliance Wiring Material) is based on a modular system where cables with an AWM approval can be made up of separate insulation and outer jacket approvals issued by the manufacturer. UL Listed involves subjecting the entire cable to UL testing.
The 2007 edition of the American NFPA 79 Electrical Standard for Industrial Machinery prohibited the use of AWM wires and cables in machinery cabling and explicitly demanded a UL Listing. This proved in many cases unpractical as for many applications there is no legislation to which a listing could be applied. For this reason, this regulation was modified in NFPA 79, edition 2012 and the use of AWMs is now permitted under certain conditions.
What is HGI insulation?
HGI is the abbreviation for High Gliding Insulation.
This special insulation material was designed by Lütze engineers especially for LÜTZE SUPERFLEX® C-track cables. Engineers concentrated on maximising the gliding ability of the cables to increase their service life when used as C-track chains. The material also displays excellent electrical properties (low dielectric constant and high dielectric strength) as well as being halogen-free. This is why Lütze uses the HGI material today for a wide range of cables not just those belonging to the LÜTZE SUPERFLEX® series.
How much electricity can a cable transfer?
The amperage range of a cable depends on the cable cross-section and the heat resistance of the insulation material as higher currents heat up the cable to higher temperatures. Selecting the correct cable is the responsibility of the system planner as the cable manufacturer is not familiar with the specific application. Details can be found in the national standards and legislations such as VDE 0298-4 or VDE 0100.
What are the advantages of halogen-free cables?
On combustion, halogens can react and form acids when combined with ambient humidity. Inhaling these types of halogenated fumes can cause fatal caustic burns to the respiratory tract. The acids also damage technical components and devices by causing premature oxidation or short circuits in electrical or electronic components.
Why is the temperature range divided into static and moving?
Flexible control cables are mainly insulated and covered with thermoplastic. When subject to high temperatures, thermoplastics become soft and malleable. This explains the various limit temperatures: with fixed installation cables it is not a problem when the plastics become soft. However, when the cables are moved, the plastic can be deformed and the cables can become damaged.
This also applies when the plastic becomes brittle at low temperatures.
What is the copper index?
As copper is a listed precious metal, the copper content in a cable is calculated depending on the current listed price. This calculation is based on the amount of copper that is present in the rated cross sections of the copper cables and shielding.
What does the cable category stand for?
The copper conductors in flexible cables usually comprise of numerous thin wires that are twisted together. In comparison to a single copper wire, in which the cross section corresponds to the sum of the single wires, twisted copper wires deliver a considerably higher ductility of the conductor and the entire cable. The international IEC 60228 standard specifies the wire thickness and electrical resistance for copper strands in various categories. The higher the category, the finer the wires:
Category 1: Massive conductors
Category 2: Multi-stranded conductors
Category 5: Finely stranded conductors
Category 6: Superfine stranded conductors
What is the difference between bending and torsion?
Different types of movement require different cable constructions. A cable with optimised bending load has different construction parameters than one designed for torsion load.
Torsion is the twisting motion with which a torque is tangential to the cable axis.
Bending is the twisting motion with which a torque is radial to the cable axis.
Is the jacket material resistant against certain chemical substances?
