A Ring Main Unit (RMU) is a compact, sealed switchgear solution used for medium-voltage power distribution, offering safe and efficient control, protection, and isolation of electrical networks. Widely adopted in urban, industrial, and utility infrastructures, RMUs are known for their reliability, minimal maintenance, and ability to ensure uninterrupted power supply. SkyPower, as the authorized distributor of Siemens in Pakistan, offers NTDC-approved Siemens 3-way and 4-way RMUs, which are factory-assembled, robust, and engineered to deliver outstanding performance under harsh conditions. These RMUs are available with voltage ratings up to 24 kV, current ratings up to 630 A, and short-circuit handling capacity of up to 16 kA. With advanced insulation options (SF6 or solid dielectric), IP65/IP4X enclosure protection, and compatibility with SCADA systems, they provide superior safety, flexibility, and integration for critical applications like power utilities, renewable energy systems, data centers, telecom infrastructure, and smart grids. Compliant with IEC 62271-200 and NTDC standards (DDS:46), Siemens RMUs come with complete technical documentation, including KEMA/CESI type test certificates and ISO-certified manufacturing assurance, making them a trusted choice for reliable and future-ready power distribution.

SkyPower’s Vacuum Circuit Breakers (VCBs) offer safe, efficient, and reliable switching solutions for medium-voltage power systems. Utilizing advanced vacuum interrupter technology to extinguish arcs within a vacuum chamber, these breakers ensure minimal energy loss, low maintenance requirements, and extended operational life. The Siemens SION 3AE8 series, distributed by SkyPower in Pakistan, exemplifies this technology with rated voltages up to 12 kV, current capacities reaching 3150 A, and a short-circuit breaking capacity of up to 40 kA, making them ideal for industrial, commercial, and utility applications. Designed for fast fault interruption and robust system protection, these VCBs feature a stored-energy spring operating mechanism, mechanical interlocks, and visible position indicators to enhance operational safety. Built to meet rigorous international standards including NTDC P:44-2018, IEC 62271-100, and VDE 0671, they are well suited for integration into switchgear panels and substations across industries such as renewable energy, oil & gas, infrastructure, and data centers. With modular design and eco-friendly operation—free from SF₆ gas—SkyPower’s Vacuum Circuit Breakers combine performance, safety, and sustainability for reliable medium-voltage power management.

The LT Service Box is designed for reliable and secure electrical power distribution, meeting international standards such as IEC 61439 and IEC 60529 to ensure high quality and safety. It is made with heavy-duty mild steel (MS) construction and powder-coated for enhanced corrosion resistance. The box supports high-performance capacity with a voltage of 415V, frequency of 50Hz, and current rating up to 400A. It is equipped with advanced safety features like IP54 protection against dust and water, HRC fuse holders, MCBs for enhanced circuit protection, and a secure double-door system with anti-tampering locks. For ease of use, it offers pole and wall mounting options, cable glands for neat wiring, and transparent polycarbonate windows for easy meter reading. This box is ideal for residential, commercial, and industrial applications, making it a comprehensive solution for efficient power distribution.

The Meter Security Box, as per specification DDS-58:2001, is built for 3-phase, 4-wire CT operated metering systems used in LT commercial and industrial environments. Constructed from high-grade 16mm steel for the body and 2.3mm steel for the door, it ensures strong physical protection. The size ranges from 600×350×1000mm and includes a lockable front door for added security. It is suitable for both wall and floor mounting, indoor or outdoor. The box is waterproof, ventilated, and features a rigid welded structure with earthing provision for safety. It is painted with three coats including zinc chromate and synthetic resin in light beige. The internal bus bars are made of 99.9% electrolytic copper (based on CT ratio), and it undergoes strict testing such as visual inspection, dimension checks, and galvanizing tests. The box is clearly marked with voltage, CT ratio, serial number, manufacturer name, and year. For safe transportation, it is packed in a wooden frame with polythene cover.
