Cable Types

Heating cables, available in various designs (sometimes depending on a specific application), can be roughly divided into two groups: serial cables and parallel cables. The latter can be further sub-divided to self-limiting cables and constant-output cables.
 

• There are serial heating cables for protection against frost and for operating temperatures reaching even 600ºC. These types can be encountered in the case of different voltages, in corrosive environments, or in high-temperature heating. MechaHeat’s product range includes many types of these cables for various applications.
• Self-limiting cables are 115V or 230V cables and may be used up to a temperature of 190ºC. We supply 8 cable types in various designs, some of which we have ready in our stock. They are used, in particular, for protection against frost and in maintaining temperatures, and also in explosion hazard areas.
• The range of constant-output cables, for standard supply voltage, includes also cables that may be used up to a temperature of 425ºC. These cables can be encountered specifically in industrial sectors. The range we offer includes 12 types of these cables. As these cables always deliver the same output, they are suitable for maintaining and warming functions.

 

Special cable elements may be created for use in places with explosion hazards. Our specialists will be pleased to advise you as to which cable type is the most suitable for you, for the above-mentioned heating by cables using high temperature and also for other possibilities. 
 
Materials used for the electric insulation and sheathing of cables are decisive for the maximum permissible temperatures and chemical resistance. The most frequently used materials are PVC, some types of polyethylene, silicon rubber, and fluoropolymers (types of Teflon).
There is also heating by cables with a metal sheath. These include, for example, cables with mineral insulation, abbreviated as MI-cables. These cables have a metal outer sheath and a heating wire set in a compacted layer of magnesium oxide and they are of a similar structure to closed tubular elements. Individual types of these cables are available with sheathing made of copper, copper-nickel, and stainless steel.
