These cables are in the voltage range of 300/500V and 450/750 V and are covered by the standards:
DIN VDE 0281-3, DIN VDE 0281-7, BS 6004, NFC 32-201-3, NFC 32-201-7, PN HD 21.3 S3 and PN HD 21.7 S2.
The cables with a rated voltage of 300/500V are intended for installation inside the devices and in luminaries. They are placed permanently in the installation pipes or other covers, only to the signalling or controlling circuits.
The cable with a rated voltage of 450/750 V are intended to place in installation pipes fixed on a surface or embedded in a surface. For fixed security of the installation inside or outside the lighting controlling devices, on an alternating voltage up to 1000 V or DC voltage up to 750 V.
In both cases, the structures are assumed to be made of a core:
- single - H05V-U (300/500V) and H07V-U (450/750V)
- rigid, multi - H05V-R (300/500V) and H07V-R or 6491X (450/750V)
- flexible, multi - H05V-K (300/500V) and H07V-K (450/750V)
These cables can also be insulated with heat resistant polyvinyl, which results in the fact that the maximum core temperature during cable operation increases from +70°C to +90°C respectively: H05V2-U, H05V2-R, H05V2-K, H07V2-U, H07V2-R and H07V2-K.
These cables can also be produced in halogen-free insulation based on DIN VDE 0282-9, BS7211 and PN-HD 22.9 S33.
For installation on a surface or in installation pipes, especially in areas at risk of fire, when the emission of harmful fumes and noxious gases must be limited.
