Remote power supply system

The "one-line dual-use" DC remote power supply system is a high-voltage DC remote power supply equipment based on a single-line series topology. Its core innovation lies in: the use of a copper core wire in the photoelectric composite cable to simultaneously complete DC power transmission and step-by-step series power supply, to achieve "one-line dual-use"-both transmission of DC power, and the use of optical fiber in the photoelectric composite cable to transmit communication signals, to achieve the same cable transmission of power and signals. Different from the traditional parallel DC remote supply, the system adopts the method of single-wire series load one by one: the front-end DC high-voltage power generator rectifies the AC power of the machine room and converts PWM into bipolar DC high-voltage power suspended to the ground, which is transmitted through a single-wire cable.

Product Overview Remote Power Supply (Remote Power Supply System) is a power supply system that transmits and receives electric energy over a long distance through power cables. Its core function is to boost and convert the standard AC or DC basic power supply in the local office room into high-voltage DC power, then transmit it to the remote end over a long distance through the cable, and then step-down convert it into the standard voltage required by the load by the remote equipment to provide stable and reliable power supply for the remote equipment. The system consists of two parts: local end equipment (boost power transmission end) and remote end equipment (buck power receiving end). The local equipment completes AC/DC or DC/DC boost conversion and outputs high-voltage direct current.

Product Overview: The railway section continuous DC remote power supply equipment is an uninterruptible DC power supply solution specifically designed for communication devices, signaling equipment, and monitoring systems along railway lines. Railway‑section equipment—such as GSM‑R fiber‑optic repeaters, distributed base stations, signal relay stations, and section surveillance cameras—is deployed in a strip‑like configuration across the extensive length of the railway line. The conventional AC power supply approach faces significant challenges, including insufficient power capacity, a limited power supply radius, large cable cross‑sections, and high capital costs. The system is designed in accordance with the “General Technical Requirements for DC Long-Distance Power Supply Systems for Railway Section Communication Equipment” and employs DC high-voltage long-distance power supply technology.

Product Overview: The long-distance power supply system for camera surveillance equipment is a specialized power solution designed to address challenges such as the dispersed deployment of front-end cameras, long power supply distances, and difficulties in obtaining power in video surveillance systems. In scenes such as expressways, smart parks, bridges and tunnels, oil and gas pipelines, urban pipe corridors, border and coastal defenses, monitoring points are often distributed in bands or planes, and the distance between adjacent points can reach hundreds of meters or even kilometers. The traditional way of taking electricity nearby faces outstanding problems such as high cost of introducing mains electricity, long construction period and difficult maintenance. The system adopts a high-voltage DC remote power supply or long-distance PoE power supply architecture, with power supplied from the central office.

Product Overview The border and coastal long-distance power supply system is an off-grid/remote power solution specifically designed for national defense duty stations, including borderlines, coastlines, islands, outposts, and radar stations. China’s land border stretches for 22,800 kilometers, and its coastline exceeds 32,000 kilometers. Many of the operational posts are located in remote areas far from the power grid, making it difficult to rely on conventional grid electricity. Diesel generators, meanwhile, face significant challenges, including high fuel transportation costs, noise pollution, and unreliable supply in adverse weather conditions. The system is based on the core requirements of "scattered points, harsh environment, unattended, and extremely high power supply reliability requirements" in border defense and coastal defense scenarios.

Product Overview: The remote power supply equipment for communication base stations (DC remote power supply system) is a specialized power solution designed to address challenges such as difficulties in base station site selection, high costs associated with utility power connection, and significant voltage drops over long-distance power distribution. The system consists of two parts: the local end machine (near-end equipment) and the remote end machine (far-end equipment), and realizes the long-distance stable transmission of electric energy through the composite optical cable or power cable. The central office equipment isolates and steps up the 48V DC base power supply (or 220V AC mains power) within the equipment room to a high-voltage DC of 250V–410V (with some models reaching up to 800V), which is then transmitted via cabling to the remote site.

Product Overview: The highway remote power supply system is a centralized, long-distance power distribution solution specifically designed for roadside equipment along highways. Its core function is to transmit standard AC power from the toll station or service area equipment room—via step-up, transmission, and step-down processes—over long distances to devices such as surveillance cameras, variable message signs, meteorological sensors, and ETC gantries installed along the roadway, providing them with a stable and reliable power supply. The system primarily consists of three major components: the central office equipment (power generator), the transmission cable, and the remote equipment (power converter). The central office equipment is deployed at toll stations or service areas along the highway to provide power.
