The Challenge

Our Skies Are Shared.
Our Infrastructure Creates
an Invisible Threat.

Across India's expanding energy network, over 90,000 circuit kilometres of high-voltage transmission lines intersect with critical wildlife habitats, migratory corridors, and protected areas. Power lines, earth wires, and stay wires are effectively invisible to birds — especially in fog, low light, and at flight speeds above 40 km/h.

The consequences extend beyond wildlife. Bird strikes on conductors trigger flashovers, line faults, and unplanned outages — creating measurable grid reliability risks and costly emergency repair mobilisations for transmission operators.

The critically endangered Great Indian Bustard — fewer than 150 individuals remaining — faces power line collision as a primary extinction threat. The Supreme Court of India has directed mandatory Bird Flight Diverter installation across GIB habitat corridors as a priority conservation measure.

This is simultaneously a conservation emergency, an infrastructure reliability challenge, and an ESG compliance imperative — requiring an engineered solution, not a compromise.

Low Visibility Hazards

Power lines, earth wires, and guy wires are thin, high-contrast against sky only under ideal conditions — and effectively invisible to birds at high speed, in fog, or at dawn and dusk.

Habitat Intersection

India's expanding energy and communication networks increasingly cross vital migratory routes, Ramsar wetlands, Protected Area boundaries, and Important Bird Areas (IBAs).

Infrastructure Risk

Bird-strike-induced conductor flashovers create real grid reliability and revenue risks for transmission utilities — beyond the conservation consequences of every avian collision.

Why These Specifications Matter

Universal 5–38mm Clamp

One device fits every conductor type across your entire network — ACSR, AAAC, OPGW, earthwires. No multi-SKU inventory complexity. Simplified procurement, reduced logistics.

-20°C to +100°C Operation

Tested across India's full climate envelope — Rajasthan desert heat, Himalayan cold, monsoon humidity. UV-stabilised polymer ensures dimensional and optical stability over 15 years.

+12,000 mm² Glow Area

Photoluminescent polymer glow at dawn and dusk — the highest-risk periods for large bird flight. No power source required. Passive protection that works precisely when it is most needed.

Hot-Stick Compatible Installation

Retrofit deployment on energised live lines — no planned outage required. Enables large-scale network rollout without the scheduling, cost, and grid-stability implications of de-energisation.

8 Type Tests per CEA Protocol

Common Questions

Frequently
Asked by Engineers
and Procurement Teams

Technical questions from transmission engineers, EPC contractors, and procurement heads — answered with the precision they require.

Ask Our Technical Team
What is a bird flight diverter and how does it prevent avian collisions?

A bird flight diverter is a device installed on overhead conductors and earth wires that increases their visual detectability to birds in flight. Birds approach power lines at speeds where reaction time is insufficient to avoid invisible conductors. Diverters provide visual contrast through retroreflection, photoluminescent glow, dynamic rotational motion, and — in LED models — active blinking illumination. This gives birds sufficient detection distance to alter their flight path safely.

Are Prakritis bird flight diverters CEA-compliant?

Yes. All Prakritis products are designed, manufactured, and tested to meet the Central Electricity Authority's Technical Specification for Bird Flight Diverters — the binding Indian regulatory standard for power line avian collision mitigation. Formal approvals have been granted by PGCIL, GETCO, and RVPN. Type test documentation is available for submission to utility procurement processes.

What conductor sizes are compatible with the universal clamp?

The universal-size clamp accommodates all conductor and earth wire diameters from 5mm to 38mm — covering ACSR, AAAC, AAC, OPGW, and standard earthwire types across sub-transmission, transmission, and EHV networks. No adapter hardware or specialist tooling is required for any standard Indian transmission line conductor.

When should I specify LED versus Non-LED diverters?

LED models (PLM/LD-V1) are recommended for high-risk zones requiring 24-hour active protection — near major migratory routes, GIB habitat corridors, airports, and areas with significant nocturnal flight activity. Non-LED models (PLM/NLD-V1) provide effective daytime and transitional-light protection through retroreflection and photoluminescence, and are optimal for standard network deployment where active illumination is not mandated. A risk-zoned approach — LED at hotspots, Non-LED on standard spans — is common best practice.

Can bird flight diverters be installed on energised (live) lines?

Yes. All Prakritis diverters are compatible with hot-stick installation procedures used by trained live-line crews on energised conductors. This eliminates the need for planned outages and enables large-scale retrofit rollout without the scheduling complexity and grid stability implications of de-energisation.

What is the warranty and expected service life?

Every Prakritis bird flight diverter carries a comprehensive 5-year product warranty from date of supply. Design life is a minimum of 15 years under operational conditions within the tested environmental parameters. UV-stabilised polymer construction and non-corrosive metallic hardware are specified specifically to support this lifecycle commitment.

What type tests have been conducted on the products?

Products undergo: Mechanical Strength (clamp slip ±25kg, pull +100kg), Vibration, Temperature Cycle (-20°C to +100°C), Heating Cycle, Radio Interference Voltage / Visual Corona, Corrosion Resistance, Accelerated Ageing, and Visual Examination tests. Full type test reports are available to procurement authorities on request.
