Underground Safety Cabinet (USC)

Underground Safety Cabinet
Company Background

Have you ever noticed electrical circuits or facilities while walking around your city or town? These facilities named transformers, responsible for distributing power to households and buildings, have become a ubiquitous presence in today's industrialized world.

While safety measures such as the installation of fire fighting boxes aim to protect people, it is essential to consider the potential dangers that these facilities pose to the public during natural disasters or heat waves.

At Korea Safety Industry Inc.(KORSI), we're committed to addressing these safety concerns. We've developed world's very first Underground Safety Cabinet(USC), which securely contains the electrical equipment needed for a city's power supply. Further, based on this technology, we also developed Underground Firefighting Equipment Cabinet(UFEC) to safely store all the firefighting equipment in it. Our products provide an added layer of protection and minimizes the risk of accidents and explosions.

Moving forward, we're dedicated to further enhancing our product, exploring collaborative opportunities with other companies, and working towards our goal of achieving eternal safety.

Underground Safety Cabinet (USC)
Introducing USC

USC for Electrical Devices

UFEC
(Underground Firefighting Equipment Cabinet)

USC is a multipurpose, multi-functional, Underground Safety Cabinet System.
It’s sole purpose is to place ground-exposed electric public devices underground for safe operation and management.
Our product is designed and composed of seven features. Key features of our product includes that it is waterproof and self ventilating.
Civil engineering, architecture, electricity, machinery, electronic communication, and IT control are integrated into our USC system making this a whole new technology.

Based on USC technology, UFEC was developed for firefighting which which will be introduced on a seprated page. We hope this innovative products serve a great purpose to our society, mainly prioritizing on the safety of the public ; starting from Korea, now worldwide.

Underground Safety Cabinet
Product Features

The Underground Safety Cabinet System has seven features that ensure an optimal environment for transformer operation :

01Water-proof Feature (IPX8):

This feature seals off water penetration through a combination of methods, including shield method, sphere waterproofing, outer wall waterproofing, insertion of sleeves, and highpressure steaming. It provides a waterproof rating of IPX 8.

02Heat Dissipating Feature:

This feature dissipates heat rising from transformers/switches using a new waterproof HVAC and heat dissipating panel to disperse heat externally.

03Moisture-proof Feature:

This feature prevents moisture and dew condensation by matching internal and external temperature through natural ventilation and heat dissipation using a new waterproof HVAC and heat dissipating panel.

04HVAC Feature:

This feature employs a waterproof mechanical Heating,Ventilation, and Air conditioning (HVAC) system with natural air circulation to maintain internal space.

05Decompression Feature:

This feature forces downward pressure in the event of a transformer explosion to prevent damage to the above surface level.

06System Control Feature:

This feature enables both internal and external control of the system via wired or wireless communications.

07Mechanical operation Feature:

The system's outer cover, inner cover (water-tight), waterproofing, and HVAC can be operated manually without power.
