Koble — Bringing Ideas to Life
Koble Impex Pvt. Ltd. designs and manufactures intelligent electronic systems for safety, reliability and performance — built in Bengaluru for the demanding environments of Indian Railways.
Sectors We Serve
Earth resistance and surge monitoring for signalling installations, traction substations and location boxes across Indian Railways.
Surge and earthing protection for marine installations operating in harsh, corrosive environments.
Reliable electrical safety for aviation infrastructure where failure is not an option.
Product Range
Flagship
Continuously measures earth resistance in real time for railway signalling and power installations. Split-core sensor with RMCU, audio-visual threshold alarms, RS485 communication, IP-54 protection. Intertek-inspected.
Centralized remote monitoring for surge protective devices. Real-time health status and early fault alerts across your entire installation — predictive maintenance instead of surprise failures.
Multi-channel online monitoring of SPD leakage current and voltage for Indian Railways and telecom towers. Continuous, precise data on surge protection performance.
Portable on-site tester for SPD component health and remaining life. Verify lightning protection systems in the field, without lab testing.
Manufacturing
Our systems are designed and built in-house to perform under extreme heat, humidity, dust and vibration — the real conditions of railway installations across India. Every flagship product is developed in direct response to railway maintenance pain points, and independently inspected for accuracy, stability and performance.
Our Unique Strengths
Solutions like the 2800KB provide continuous real-time data, enabling proactive maintenance and reducing risks.
Designed to perform in India’s challenging railway environments — extreme heat, humidity, dust and vibration.
First-of-their-kind innovations, developed in direct response to railway pain points, with no current direct alternatives in the Indian market.
All major components are conceptualized internally, allowing rapid iteration, deep integration with railway needs, and compliance.
