As a vital component of the power system, the safe and stable operation of substations directly impacts the reliability of electricity supply. During major maintenance activities at substations, operational personnel must implement safety measures, including the installation of safety barriers to isolate work zones and prevent unauthorised access to hazardous areas. However, conventional safety barriers typically employ metal support poles combined with shielding panels, presenting issues such as time-consuming installation and dismantling, along with labour-intensive requirements.

To address these challenges, Marstone has introduced an outdoor underground retractable safety barrier. Utilising pre-embedded railings and electromechanical lifting technology, this system enables rapid deployment of safety barriers, significantly enhancing operational efficiency.

Addressing the aforementioned challenges, Marstone's underground retractable safety fence incorporates pre-embedded railings and a lifting system to enable rapid barrier deployment.
Its core design features include:
Pre-embedded railing structure: Pre-embedded railings are installed within substation maintenance zones, with retractable sections prefabricated underground. This occupies no surface area and does not interfere with daily operations.
Automated control system: Electromechanical drives and counterweight mechanisms enable automatic barrier elevation. Operatives simply press a button to extend the telescopic railings (typically 1.4-1.8 metres) from their embedded positions, establishing zone isolation.
Practical application demonstrates that Marstone's retractable safety fences have achieved favourable outcomes in multiple substation pilot schemes. For instance, one substation implementing these barriers during major maintenance reduced safety measure deployment time by 70%, decreased manpower requirements by 50%, and recorded zero safety incidents.
