Cable properties explained

For buyers looking for proven, safe and reliable control cables, TME recommends exploring the properties of Alpha Wire’s Pro-Met and Pro-Tekt series


To keep electrical resistance as low as possible, Alpha Wire uses copper or tinned copper as the core material, which also makes soldering easier. Copper also resists stretching and bending without damage. Depending on the application, the manufacturer offers cables with two to twelve cores in the Pro-Met series and two to eight in the Pro-Tekt series.


Regarding insulation materials, both series are protected with polyvinyl chloride (PVC). This insulation ensures proper cable flexibility and protects the user from contacting live conductors. On rated voltage, Pro-Met and Pro-Tekt cables work at 300/500V and 300V respectively.


Operating temperature limit is -30 to 70°C for the Pro-Met series and up to 105°C for the Pro-Tekt series.


Alpha Wire cables are protected from chemical substances such as oils (including mineral) and UV radiation. Likewise, Alpha Wire offers cores with and without protection. Protective cores makes it possible for the cable to be used in installations operating in humid rooms and spaces exposed to contact with water.


Alpha Wire offers standard or shielded cables to protect signals from external interference. The shield also provides additional protection against electric shock and short circuits. Regarding fire-resistant properties, both series do not cause the spread of fire along the installation.
