JDZW3-36 outdoor epoxy resin casting Voltage transformer JDZW3-36 gawas na voltage transformer nga gipula sa epoxy resin

Product Overview

JDZW3-36 voltage transformer, outdoor epoxy resin casting and double pole insulated VT, is widely used for measuring current, electric energy and protective relaying in the isolated neutral system with the frequency 50Hz or 60Hz and insulation voltage 36 kV (Up to 40.5kV).

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

Key Features

• Excellent Outdoor Insulation Protection：Ang JDZW3-36 ay gumagamit ng high-quality epoxy resin bilang pangunahing insulating material, na may silicone rubber coating sa labas. Ang tradisyonal na proseso ng epoxy resin casting sa loob ay nagse-cure sa insulation at electrical performance ng transformer. Ang silicone rubber ay may excellent arc resistance, hydrophobicity, at climatic adaptability, na nagbibigay-daan para ang equipment ay maaaring mag-operate normal sa mataas na altitude, high-salt fog, ulan, at malakas na UV environments. Kahit na may mga system faults na nagdudulot ng pagsabog, ang external silicone rubber structure ay nag-restrain sa internal resin, na nagbabawas ng splashing damage sa mga taong paligid, hayop, o equipment.

• High Precision & Low Partial Discharge：Ang vacuum casting process ay nag-aachieve 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 sumasalamin sa high-precision metering at protection needs upang ibigay ang reliable voltage data para sa 36kV at below 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 nag-extend ng service life at nagse-secure 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 sumasalamin o lumalampas sa relevant standards—lalo na angkop para sa high-pollution areas. Ang surface ay dumaan sa special treatment upang pa-enhance ang anti-fouling performance at bawasan ang flashover risks.

• Durable Metal Components：Ang lahat ng metal components ay hot-dip galvanized upang pa-enhance ang corrosion resistance, na nakakatagal sa long-term outdoor exposure sa hangin, ulan, at araw—na nagse-secure ng reliable long-term service sa outdoor environments.
