Description
Product Overview
The RR Kabel FR HSF 2.5 sq mm Yellow/Green Earth Wire is a premium-grade flexible copper cable from RR Kabel’s HSF (Hazardous Substances Free) range — engineered for safe, compliant earthing in modern residential, commercial, and industrial electrical systems. The distinctive Yellow/Green dual-colour insulation is the internationally recognised colour code for earth and ground conductors, making it instantly identifiable in any switchboard or panel installation.
What sets the FR HSF range apart from standard FR wires is its complete freedom from 245+ hazardous substances including lead, cadmium, mercury, and other RoHS-restricted materials. This makes it suitable for green building projects, export-oriented manufacturing facilities, hospitals, schools, and any installation where material safety and environmental compliance are required alongside electrical performance. Manufactured at RR Kabel’s ISO 9001 certified Vadodara plant and carrying ISI, CE, and CPR marks, this wire represents RR Kabel’s commitment to being the Safest of All.

Why Choose RR Kabel FR HSF Earth Wire?
- Hazardous Substances Free: Free from 245+ harmful substances including lead, cadmium, mercury, and all RoHS-restricted materials — safe for people, safe for the planet
- 100% Electrolytic Copper: Superior purity copper conductor ensures maximum conductivity and reliable fault current dissipation — critical for effective earthing performance
- Class 5 Flexible Construction: Fine multistrand conductor is easy to route through conduits, around panels, and into terminal blocks without breaking or kinking
- FR-PVC Insulation: Flame Retardant insulation self-extinguishes when ignition source is removed, limiting fire spread even in earth wire runs
- Triple Certified: ISI mark (IS 694), CE mark (European compliance), and CPR (Construction Products Regulation) — accepted in Indian and international projects
- Safest of All: RR Kabel’s flagship safety positioning backed by verified testing — the right choice for any installation where safety is non-negotiable
Yellow/Green Colour — Earth Wire Standard
Yellow/Green dual-colour insulation is the universally recognised identifier for earth and protective conductors as per IS 3043, IEC 60446, and the National Electrical Code. Using Yellow/Green exclusively for earth connections is not just best practice — it is a mandatory requirement in most electrical installation standards. Never use Yellow/Green wire for phase or neutral connections. This colour coding ensures that any electrician or inspector can immediately identify the earth conductor in any panel, junction box, or switchboard.
FR HSF vs Standard FR Wire — What Is the Difference?
Standard FR (Flame Retardant) wire meets IS 694 fire safety requirements but may contain trace amounts of regulated heavy metals in the PVC compound. FR HSF (Hazardous Substances Free) goes further — the insulation compound is reformulated to eliminate 245+ hazardous substances, making it RoHS compliant and suitable for projects with strict environmental or health safety requirements. For standard residential wiring, regular FR wire is adequate. For hospitals, schools, green buildings, or export projects, FR HSF is the correct specification.

Frequently Asked Questions
What does FR HSF mean in RR Kabel wires?
FR HSF stands for Flame Retardant, Hazardous Substances Free. It means the wire’s insulation meets IS 694 flame retardancy requirements and is also free from 245+ hazardous substances including lead, cadmium, and mercury. This makes it RoHS compliant and suitable for environmentally sensitive and health-critical installations such as hospitals, schools, and green-certified buildings.
Why is earth wire always Yellow/Green in colour?
Yellow/Green is the mandatory colour for protective earth conductors as per IS 3043 (Indian Standard for Earthing), IEC 60446 (international colour coding standard), and the National Building Code of India. This dual colour makes earth wires instantly distinguishable from phase (Red/Blue/Black) and neutral (Black/Grey) conductors, preventing dangerous misconnections during installation and maintenance.
Is this wire suitable for solar and EV charging installations?
Yes. The RR Kabel FR HSF 2.5 sq mm Yellow/Green wire is suitable for earth bonding in solar PV installations and EV charging station wiring. Its RoHS compliance and CE marking also make it acceptable for projects following international installation standards. For DC earth connections in solar systems, always consult your system designer for the correct conductor size based on fault current ratings.
What is the difference between Class 2 and Class 5 conductor for earth wire?
Class 2 conductors are solid or have fewer, thicker strands — used in fixed house wiring. Class 5 conductors like this cable have many fine copper strands, making them flexible and easy to terminate in panel earth bars, equipment terminals, and DIN rail mounted earth terminal blocks. For panel wiring and equipment earthing, Class 5 multistrand is always preferred for ease of installation and secure terminal connections.
