Lighting Substation

Unlock advanced power distribution and exceptional lighting control with our state-of-the-art Lighting Secondary Substation (LSS). Crafted as a specialized Unit Substation (USS), the LSS redefines efficiency, safety, and aesthetics in urban centers. Engineered and rigorously tested according to IEC 62271-202 standards, this compact marvel seamlessly integrates a distribution transformer, low voltage lighting control switchboard, connections, and associated equipment.

Key Product Features

Unparalleled Safety and Aesthetics

Situated in high-density urban environments, the LSS prioritizes personal safety and aesthetics. Its self-supporting enclosure safeguards against environmental factors and unauthorized access, upholding uncompromising standards in both form and function.

Modular Roof Design

Effortlessly adapt to evolving equipment needs with the LSS's modular roof design. The detachable constructional component can be easily lifted off on-site for swift equipment replacement, minimizing downtime and maximizing efficiency.

Seamless Accessibility

Designed with user convenience in mind, the roof fixation mechanism ensures swift and hassle-free access. Quick detachment empowers your team to efficiently handle maintenance and upgrades without complications.

Operational Convenience

The doors are equipped with door stoppers, ensuring they remain securely open during operation and maintenance. Embrace flexibility with the standard 3-point locking system, or choose from various locking variants as per your requirements.

Illuminated Compartments

Experience enhanced visibility during operation with the compartments' integrated door limit switch and panel light. These features activate upon door opening, illuminating your workspace and streamlining maintenance tasks.

Proven Performance

Tailored Connectivity

The connection between the distribution transformer and the medium voltage (MV)/LV equipment adapts to your project specifications. The MV side of the transformer boasts a secure connection through pre-molded, cold shrink, or heat shrink cable heads, ensu

Dynamic LV Switchboard

The LV switchboard's versatility shines, as it seamlessly connects via busbar or insulated cable, tailored to the transformer's rated power. This adaptability optimizes power distribution, catering to various scenarios and requirements.

Saudi Municipality Compliance

The LSS comes equipped with a branch breaker configuration in alignment with Saudi municipality lighting standards. With options accommodating up to 24 branch breakers featuring two 150A-AC1 @ 415VAC contactors, or up to eight branches with similar contac
