Product descriptions from the supplier
Description
General：
VD4 series circuit-breakers are devices under vacuum for indoor installation. Please contact ROCKWILL for special installation requirements. VD4-R series medium voltage vacuum circuit-breakers with lateral operating mechanism for indoor installation feature the separate pole construction technique.Each pole houses a vacuum interrupter which is encased in the resin when the cylinder is moulded thanks to a special manufacturing process. This construction method protects the vacuum interrupter from shock, pollution and condensation.The operating mechanism is the trip-free stored energy type with independent opening and closing regardless of the opera-tor’s action. The operating mechanism is widely used in all VD4-R series circuit-breakers with frontal control.The circuit-breaker can be remote controlled when fitted with dedicated electrical accessories (gearmotor,opening and closing release).
The operating mechanism, the three poles and the current sensors (if provided) are installed on a metal frame without wheels. The construction is particularly compact, sturdy and of limited weight.VD4-R series circuit-breakers with lateral operating mechanisms are life-long sealed pressure devices.(Standards IEC 62271-100)

Strange Devices on Transmission Lines: 5 Little-Known Practical Functions（1）1 Aviation Warning SpheresAviation warning spheres, also known as reflective safety spheres, are used on overhead transmission lines near airports, especially on extra-high-voltage (above 220kV) lines and river-crossing transmission lines. Highly visible aviation marker spheres (aviation warning spheres) must be installed along the lines to provide warning signals.The aviation marker sphere (aviation warning sphere) has a diameter of ф=600mm. The sphere can be manufactured in various bright coloLeon09/04/2025 -
Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -

Analysis of Accident Handling in Transmission LinesAnalysis of Transmission Line Fault HandlingAs a fundamental component of the power grid, transmission lines are widely distributed and numerous, often exposed to diverse geographical and climatic conditions, making them highly susceptible to faults. Common causes include overvoltage, pollution flashover, insulation damage, tree encroachment, and external damage. Line tripping is one of the most frequent faults in power plant and substation operations, with fault types including single-phase-to-Leon09/04/2025 -
The difference between transmission and distribution linesTransmission lines and distribution lines are both used to carry electrical power from one location to another.
