JDZW3-36 outdoor epoxy resin casting Voltage transformer JDZW3-36 panlabas na epoxy resin casting Voltage transformer

Product Overview

JDZW3-36 voltage transformer, outdoor epoxy resin casting at double pole insulated VT, malawid na ginagamit para sa pagsukat ng kasalukuyan, enerhiya, at protective relaying sa isolated neutral system na may frequency na 50Hz o 60Hz at insulation voltage na 36 kV (Up to 40.5kV).

Ang iron core ay gumagamit ng advanced cold-rolled silicon steel sheet. Ang high voltage outgoing line ng primary winding ay inilabas mula sa itaas ng produkto; ang outgoing line ng secondary winding naman ay inilabas mula sa transverse side ng produkto.

Key Features

• Excellent Outdoor Insulation Protection：Ang JDZW3-36 ay gumagamit ng high-quality epoxy resin bilang pangunahing insulation material, na may silicone rubber coating sa labas. Ang internal traditional epoxy resin casting process ay sigurado ang insulation at electrical performance ng transformer. Ang silicone rubber ay may excellent arc resistance, hydrophobicity, at climatic adaptability, na nagbibigay-daan sa equipment na mag-operate nang normal sa high-altitude, high-salt fog, ulan, at strong UV environments. Kahit na may sistema fault na nagdudulot ng explosion, ang external silicone rubber structure ay nakakapigil ng internal resin, na nagbabawas ng splashing damage sa mga taong paligid, hayop, o equipment.

• High Precision & Low Partial Discharge：Ang vacuum casting process ay nagpapahintulot ng uniform electric field distribution na may low partial discharge, na nagbibigay ng precise voltage measurement. Ang voltage ratio error ay kontrolado sa minimal range, na sumasakto sa high-precision metering at protection needs upang magbigay ng reliable voltage data para sa 36kV at ibaba power systems.

• Fully Enclosed & Sealed Design：Ang primary at secondary terminals ay completely sealed upang maiwasan ang pagpasok ng dust, moisture, at impurities, na nag-iwas sa degradation ng electrical performance dahil sa external factors. Ito ay nagpapahaba ng service life at nagbibigay ng stable operation sa complex outdoor environments.

• Strong Anti-Fouling Capability：Ang external insulation ay may mataas na dry arc at large creepage distance, na ang creepage distance ay sumasakto o lumalampas sa relevant standards—lalo na ang suitable para sa high-pollution areas. Ang surface ay dinala sa special treatment upang paigtingin ang anti-fouling performance at bawasan ang flashover risks.

• Durable Metal Components：Lahat ng metal components ay hot-dip galvanized upang paigtingin ang corrosion resistance, na matitiis ang long-term outdoor exposure sa hangin, ulan, at araw—na nagbibigay ng reliable long-term service sa outdoor environments.
