LoRad stands for Low Radiation of electric and magnetic alternating fields. Protects your equipment from radiated mains noise as well as from RF pick-up. The screen protects from the electric fields and the short pitch twisting protects from and cancels the magnetic fields. This will typically result in a cleaner sound and more accurate transients, which in turn give you a tighter bass, better 3-Demension presence and stereo definition. Closer to the truth. Besides this, the human health aspect should be considered. It is scientifically proven that magnetic alternating fields affect the human cell growth.
Supra LoRad is the sole audio grade mains cable in the world with full European safety approval. SUPRA’s screening concept is patented worldwide by Tommy Jenving.
Applications
- Hi-Fi and studio systems
- Medical equipments
- Measurement and laboratory equipments
- For people sensitive to electric/magnetic radiation
- In any application where electric/magnetic interference is critical
The Lorad Concept
LoRad is a mains flex with patented screening for connection of audio equipment to 230V mains. The screening minimizes the interference from electric alternating fields, protecting from both radiation and pick-up. For cancelling of magnetic alternating fields the LoRad is cabled with a short pitch twisting. LoRad, the only approved screened mains flex. Owing to the patented design the drain wire is eliminated and instead the screen is automatically connected to earth via a green semi-conductive plastic on the earth conductor. This enables the cable to pass the flex test of 2x30,000 bending strokes without damage, for safety approval, whereas a drain wire would cut through the insulations during the test. The LoRad is very flexible owing to the multiwire conductors. Each conductor is made of 320 tin plated copper wires.
- LoRad stands for Low Radiation of electric and magnetic alternating fields
- The screen protects your equipment from radiated mains noise and from RF oick-up.
- Short pitch twisting of the cores cancels the magnetic alternating fields.
- This will result in a cleaner sound and more accurate transients.
The biggest differences between Lorad MkII and the old Lorad cable, is that it is now based on SUPRA’s unique Nylon screen concept. Semiconducting Nylon Screen provides improved shielding properties, bending strength, environmental immunity, higher tensile strength and less microphonic effect. The Nylon screen is connected with a drain-wire. We have tested and evaluated all known types of screens for making such a good cable as possible. SUPRA’s semi-conductive Nylon screen was the only one that passed the safety requirements and, moreover, its shielding properties was best in test. LoRad MkII is tested and certified by Intertek Sweden, meeting the European safety regulation HD21.5 S3.
The cable must use a grounded outlet for the full Lorad affect.
The drain wire should be connected within the plug at the ground wire terminal on the source side (wall socket).
