Hutchison Telecommunications Hong Kong Limited (HTHK) has deployed its advanced 5G ‘Smart Inspector’ Robotic Solution to The Hongkong Electric Co., Ltd (HK Electric), aiming to conduct continuous monitoring and examination of a confined cable tunnel.

The implementation of the Smart Inspector is crucial for continuous surveillance and inspection of the cable tunnel, guaranteeing the safety of power supply equipment and upholding dependable electricity distribution. This system utilizes high-speed, low-latency 5G technology, significantly enhancing patrol efficiency within the enclosed tunnel.

Transforming Smart Cable Tunnels

The cable tunnels play an essential role in HK Electric's power transmission and distribution network, and they can be quite challenging to inspect manually due to the confined spaces. HK Electric intends to transform these tunnels into ‘smart cable tunnels’ by incorporating the Smart Inspector Robotic Solution.

The solution was deployed for the first time at a cable tunnel in Cyberport, allowing the robot to conduct inspections—a task usually completed by certified workers. The robot is equipped with cameras, gas, humidity, and temperature sensors, allowing it to safely navigate the tunnel environment and gather important data.

Jess Mak, HTHK Senior Vice President of Enterprise Market, reiterated the company’s dedication to promoting digital transformation across various industries with solutions such as the Smart Inspector.

“The Smart Inspector Robotic Solution was tailored to help make cable tunnel inspections at HK Electric more convenient and flexible. It also helps to ensure staff safety during inspections in an enclosed space, showcasing the scalability and possibility of 5G,” said Mak.

HTHK's 3Business successfully installed 5G receivers into the cable tunnel, enabling the seamless real-time transmission of high-definition images and data. This solution highlights the versatility of 5G robots in various industries, including retail, catering, and property management, contributing to the advancement of Hong Kong's smart city development.

The success of the Smart Inspector Robotic Solution highlights the effectiveness of the ‘Subsidy Scheme for Encouraging Early Deployment of 5G,’ led by the Office of the Communications Authority. Under the scheme, the government subsidizes 50% of the actual cost directly relevant to the deployment of 5G technology in an approved project, subject to a cap of USD 500,000.
