What is NYBY Cable?
NYBY Cable is a 0.6/1kV Class 2 stranded copper conductor PVC insulated double steel tape armoured (STA) power cable manufactured according to IEC 60502-1, VDE 0276-603, and IS 1516.1 standards. It is engineered specifically to supply low-voltage power across industrial plants, utility substations, and civil infrastructure operating under harsh physical environments.
The cable construction consists of high-purity stranded copper conductors, protective PVC insulation, an extruded PVC filler bed, double galvanized steel tape armouring, and an outer flame-retardant black PVC jacket. The counter-wrapped steel tapes form a continuous mechanical guard that absorbs high radial impact and earth compaction forces, preserving electrical performance during direct burial or channel laying.
NYBY Cable Construction
- Conductor
- Class 2 stranded plain copper conductor per IEC/EN 60228, providing high conductivity and structural reliability.
- Insulation
- PVC (Polyvinyl Chloride) compound formulated for continuous operating loads up to +70°C.
- Inner Filler
- Extruded PVC (Polyvinyl Chloride) filler bedding the core assembly into a smooth round foundation.
- Armour Layer
- Double galvanized steel tape (STA) wrapped counter-helically for full circumferential mechanical crush protection.
- Outer Sheath
- Flame-retardant black PVC (Polyvinyl Chloride) compliant with IEC 60332-1.
- Core Identification
- 2 core: Brown, Blue; 3 core: Brown, Blue, Green/Yellow; 4 core: Brown, Black, Grey, Green/Yellow; 5 core: Brown, Blue, Black, Grey, Green/Yellow.
Applications
NYBY 0.6/1kV Armoured Cable is engineered for indoor, outdoor, and subterranean energy distribution where mechanical damage risk is elevated. Key application environments include:
Power Generating Stations & Switchgear: Connecting low-voltage control circuits, distribution boards, and transformers inside utility plants and switchgear rooms.
Subterranean Channels & Cable Ducts: Installed inside direct burial earth trenches, subterranean concrete channels, and protective municipal conduits.
Industrial Manufacturing Facilities: Routing heavy power feeds along open cable trays, equipment trenches, and factory floors subject to physical impact.
