In 33kV/35kV high-voltage outdoor distribution systems, voltage transformers (PTs) are core equipment for energy metering, voltage monitoring and relay protection, directly affecting the accuracy of electricity billing and the rapid clearing of grid faults. They must have extremely high measurement accuracy, long-term stability, and strong environmental adaptability to cope with global complex climate challenges including high temperature, high humidity, 鹽霧, heavy pollution, and high altitude. Their performance directly determines the accuracy of measuring instruments and the reliability of relay protection actions. Traditional oil-immersed PTs are plagued by oil leakage, rapid oil aging, accuracy drift, high pollution flashover risk and cumbersome operation and maintenance, especially in coastal salt spray, heavily polluted and plateau low-temperature areas, which are difficult to meet the harsh requirements of outdoor high-voltage scenarios.

The JDZW-35R dry-type outdoor voltage transformer is an ideal replacement for oil-immersed PTs, tailored for oil-free medium and high-voltage outdoor scenarios. As a fully enclosed dry-type high-voltage transformer, it has dual voltage compatibility for 33kV (36kV insulation level) and 35kV (40.5kV insulation level), adapting to power grid standards in different countries and regions. Core advantages are as follows:

1. Dual Voltage & Multi-Accuracy Classes (Global Adaptation)：Standard 35kV/40.5kV insulation level, customizable 33kV/36kV insulation version, adapting to power grid voltage requirements in different countries and regions; Accuracy classes cover Class 0.2 (高精度計量), Class 0.5 (general metering), Class 1 (monitoring), Class 6P (relay protection); JDZW-35R is equipped with a residual winding (100/3V) for earth fault protection, meeting the metering and protection needs of various medium and high-voltage distribution networks around the world.
2. Core Function (Fit for Power Grid Needs)：Steps down 33/35kV high voltage to 100V/√3 or 100V standard secondary voltage for energy meters, protection relays and monitoring systems, complying with the core function positioning of high-voltage transformers to facilitate measurement, protection and use. Strictly prohibited from short-circuit operation and must be protected by dedicated fuses. Hermetically sealed epoxy casting structure completely eliminates oil leakage and moisture ingress, achieving true maintenance-free operation and greatly reducing the operation and maintenance costs of global users.
3. Structural Reliability (Core Advantages of Dry Type)：Vacuum casting with outdoor-grade UV-resistant epoxy resin, integrating primary/secondary windings and core into one package, which is a fully enclosed high-voltage transformer, isolating the impact of harsh external environments. Three-limb laminated silicon steel core with low loss and high efficiency; oxygen-free copper windings with high insulation strength and stable transmission. Integrally formed shell with standardized mounting flange, sealed secondary terminal box and grounding bolt. Sufficient creepage distance to meet pollution degree Class Ⅳ, 防污閃, salt spray resistance and UV resistance, suitable for various complex outdoor environments around the world such as coastal areas, industrial zones and plateaus.
4. Flexible Installation (Fit for Global Scenarios)：Supports outdoor pole-mounted vertical/horizontal installation and substation floor installation, much lighter than oil-immersed PTs, with standardized mounting holes and no special tools required, adapting to different global terrains (plains, plateaus, coastal areas) and power grid layouts. Fully sealed protection for secondary terminals, 接線簡單, which can quickly adapt to wiring standards in different countries and reduce installation costs.
5. 環境適應性 (Covering Global Extreme Scenarios)：Operating temperature -40℃~+40℃, adapting to global different climate zones such as frigid, tropical and temperate zones; altitude ≤4000m, customizable plateau type (>2500米) adapting to plateau power grids; 抗震≤8度, adapting to seismic-prone areas; customizable salt spray type (coastal area), heavy pollution type (industrial area); Compliant with GB 1207, 國際電工委員會 61869-1/3 international standards, passing all tests including lightning impulse, power frequency withstand voltage and partial discharge, meeting the power grid access standards of most countries in the world.
6. 應用場景 (Global Coverage)：35kV substation bus voltage monitoring, pole-mounted high-voltage metering boxes (replacing oil-immersed PTs), wind/solar power station grid-connected metering, high-voltage distribution networks in industrial parks, railway traction substations, outdoor power grids in high-altitude, coastal and heavily polluted areas. Suitable for global medium and high-voltage distribution scenarios including Asia, 非洲, the Middle East, Europe and Australia, it is the preferred equipment for oil-free upgrading of outdoor high-voltage distribution networks.
