No, they are not. Many manufacturers mark the cable according their needs including the information that they decide, depending on the case. However there are standards that establish specifically the minimum requirements of marking case-by-case.
Cables RCT complies with the current manufacturing Regulations and Standards and has got available the most prestigious national and international certificates and homologations marking even its conductors according to more strict requirements.
More specifically, which information includes Cables RCT in the marking? The standard requires the cable to be provided with the following information:
Manufacturer’s name identification
Standard of applicability of the cable
And in case of 0,6/1 kV voltage cables.
Cable’s construction, indicating cores number and nominal cross-sectional area.
Besides, Cables RCT provides additional information of interest like its website address.
Which distance establishes the standard between markings?
The standard establishes the distance between the end of a mark and the beginning of the next identical mark to make an easy identification of the cable during its handling and installation. This distance is determined according to the voltage cable.
Cables with a rated voltage up to 750 V shall have a maximum distance between marks of 275 mm.
Cables with a rated voltage of 0,6/1kV shall have a maximum distance between marks of 550 mm.
Cables RCT guarantees the compliance with normative marking distance during the marking process by predetermined security margins.
Fitters and electricians that need to make additional marks with ink on the halogen-free cable that are different from the ones printed during marking process, can they do it directly on the insulation or sheath of the conductor?
Halogen-free compounds that are used in the manufacturing process of this range usually cause problems during subsequent markings with ink after manufacturing process.
Which answer offers Cables RCT to professionals that require this later marking to be different from the manufacturing process?
The R+D+I department has developed new formulations of halogen-free compounds becoming into insulations and sheaths that allow an ink-marking during handling or assembling process after the cable manufacture and remaining long-lasting and stabile fixed. These special compounds are known as Marking Grade.
Does Cables RCT have Marking Grade halogen-free cables in stock?
Not usually because the customer needs are usually for specific projects requiring so specific and determined quantities of certain cables. Therefore, most of the times, it is necessary to request a specific manufacturing period for every cable.
Does the halogen-free cable have the same price with the special compound marking Grade?
The special compound Marking Grade incorporates a series of substances that partially increase the cost of the insulation and/or sheath so this will be reflected in the final price of the product, being necessary to request a quotation for the project case by case with the aim of adjusting the price to every situation.
