Intelligent PDU and Ordinary PDU Structure
The difference between smart PDU and ordinary PDU is mainly reflected in the intelligent functions. A rack mount power strip, or rack power distribution unit (PDU), is a device fitted with many outlets that distribute electric power to servers, storage devices, and networking equipment located within racks or cabinets in a data center. Driven by the growth of hyperscale cloud, edge computing, and AI workloads, rack-level power distribution has become a strategic priority. Intelligent PDUs (also known as "smart PDUs") collect data on various power metrics and enable the monitoring, management, and control of the power used by IT equipment.

Malta Bridge Structure Design
The St Elmo Bridge is a single-span arched truss steel footbridge leading from the foreshore of Fort Saint Elmo in Valletta, Malta, to the breakwater at the entrance of the Grand Harbour. It was constructed in 2011–12 to designs of the Spanish architects Arenas & Asociados. The unique Valletta Grand Harbour (today UNESCO World Heritage Site) has been used as a port since Roman Empire times thanks to its magnificent natural characteristics, with a number of inlets which provide adequate shelter to naval vessels. The Msida Creek Flyover forms part of a €35 million national infrastructure project aimed at modernising one of Malta's most strategic and heavily trafficked transport corridors. After months of dedicated effort, the team at General Maintenance Ltd, in collaboration with several subcontractors, has successfully completed the design, fabrication, installation, electrical works, and finishing of a 110-meter curved steel bridge. An opening near its land end was left to prevent water stagnation and shorten routes for smaller crafts.

10kV High Voltage Busbar Structure
A 10KV busbar duct system (also known as bus trunking) is the backbone for safely and efficiently transmitting large currents at 10,000 volts, commonly found in electrical substations, heavy industrial plants, data centers, and large-scale commercial infrastructure. 1) One package contains 2 busbar supports including inlay parts for bar thickness 5 mm and lateral finger-safe covers. This is the definitive technical drawing for a 10KV Busbar Duct, an essential component for medium-voltage (MV) power distribution networks. Busbars simplify high-current distribution, reduce clutter, and can improve reliability if sized correctly. To connect various high voltage (HV) components to the HV system, TE also delivers a wide variety of busbars. The utility model discloses a high-voltage 10KV tubular bus, which comprises an insulating shell, an insulating inner layer and a cable core, wherein the insulating inner layer is sleeved on the outer surface of the cable core, a radiating pipe layer is sleeved outside the insulating inner layer.

Principle and Structure of Relay Protection
The protective relay is used to detect abnormal conditions within the electrical circuits by measuring the different electrical quantities constantly under normal as well as fault conditions. In electrical power system design, the ANSI codes indicate what features a protective device supports like a relay/circuit breaker. ANSI codes are very useful in identifying medium voltage-based microprocessor devicefunctions. Additionally, relay testing on a normal basis is required to make sure the right operation is maintained.
