Overview – What is i-LinkBox™?

It is a Link Box with special sensors which provides online alarming integrated to existing control system.
This user-friendly alarm system can continuously monitor various parameters, including the PD level occurring in the HV cable itself, joints, or terminations.
By replacing existing Link Boxes with Intelligent Link Boxes, cable system will be SMART and failures can be predicted with an early alarm system.

i-LinkBox™ Innovation Summary Compared to Conventional Link Box

Feature	Standart Link Box	i-LinkBox™
PD Monitoring	None	Continuous monitoring with HFCT sensors
Water Ingress Detection	Manual inspection	Automatic sensor with alarm
SCADA Integration	None	Full integration (IEC 60870-5-104), MQTT
Power Supply	Grid-Dependent	Solar panel, energy harvesting from HVAC cable, hybrid cable
Alarm System	None	Multi-sensor alarms (PD, temperature, water, cover, pressure, etc.)
Temperature & Humidity Monitoring	None	Internal sensors with real-time monitoring
Cover Security	Physical inspection	Cover sensor triggers alarm / Real-time monitoring
SVL Status Monitoring	Manual test	Impulse counter / Real-time monitoring
Pressure Monitoring	None	Internal sensor detects arc pressure / Monitoring
Maintenance	Reactive (after fault)	Proactive, predictive maintenance reduces downtime, cost & frequency
Sustainability	Low	High, RoHS-compliant, energy efficient
Cost Savings	High operational costs due to frequent inspections and failures	Significantly reduces maintenance & operating costs
