JDZV8-12R transformator tensiometri resina epoxi

Product Overview

JDZV8-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor for measuring current, electric energy and protective relaying in single-phase or three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 12kV.

The product has the feature of high reliability, low magnetism of core, large creep distance of external insulation and maintenance free etc.

Key Features

• Compact and Lightweight Design：With a highly compact structure, its volume is reduced by 40% and weight by 50% compared to similar products. This enables easy installation in space-constrained scenarios like switchgear and ring main units, saving both equipment layout space and installation costs.
• High Insulation Strength and Safety：The epoxy resin insulation system withstands 12kV rated voltage and 75kV lightning impulse voltage, with partial discharge ≤10pC. It effectively prevents phase-to-phase short circuits and ground breakdown. The built-in overvoltage protection fuse quickly cuts off the circuit during faults, ensuring system safety.
• Wide Temperature Range Adaptability：Operating within -40℃ to +70℃, it suits extremely cold or high-temperature regions. The epoxy resin material features excellent thermal stability, eliminating long-term aging or cracking risks, with a service life exceeding 30 years.

Main technical parameter

• Highest voltage for equipment: 12kV
• Rated primary voltage: 11kV
• Rated secondary voltage: 100/220V or 110/220V or 100V or 110V.
• Technical standard accords with IEC 60044-2:2003 Part2 Instrument transformers-Part2: inductive voltage transformers

Remarks: Upon request we are glad to offer transformers according to other standards or with non-standard technical specs.

Product Overview

JDZV8-12R transformator voltus, cum resina epoxy et constructio tota clausa, adhibetur intus pro mensura currentis, electricitatis et protectionis in circuitu AC uniphasico vel tripasico cum frequentia 50Hz vel 60Hz et maxima voltagine apparatu 12kV.

Hoc productum habet caracterem alti fidei, parva magnetismi nucleo, magnam distantiam insinuationis externae et absque cura.

Characteres Principales

• Design Compactus et Levis：Cum structura valde compacta, volumen eius diminuitur per 40% et pondus per 50% comparatum cum similibus productis. Hoc facit facilem installationem in locis angustis sicut commutatrices et unitates anularum, servans spatium dispositionis apparatorum et costus installationis.
• Fortis Insulatio et Securitas：Systema insolationis resinae epoxy sustinet voltaginem nominalem 12kV et impulsionem fulminis 75kV, cum dispergimento partiale ≤10pC. Praevent efficaciter intercircuitus inter phasos et rupturas ad terram. Fusibulum protectionis excessus voltaginis internum cito dissecat circuitum in casu defectus, securitatem systematis assecurans.
• Adaptabilitas Latitudinis Temperaturarum：Operatur intra -40℃ ad +70℃, conveniens regionibus valde frigidis vel calidis. Materialis resinae epoxy habet excellentem stabilitatem thermicam, eliminans periculos longinquorum aeviorum vel ruptrurarum, cum vita servitii superante 30 annos.

Parametri Technici Principales

• Maxima voltagine apparatu: 12kV
• Voltagine primaria nominale: 11kV
• Voltagine secundaria nominale: 100/220V vel 110/220V vel 100V vel 110V.
• Standard technicus concordat IEC 60044-2:2003 Pars 2 Transformatores instrumentorum-Pars 2: transformatores voltus inductivi

Notae: Si petatur, libenter offerimus transformatores secundum alios standardes vel cum speciebus technicis non-standard.
