Conspectus

Le unitate de anello TSTY a insulation solide redefinit le distribution secundari a 12 kV per integrar omne partes vive primari in modulos de resina epoxy colata in vacuo, operative a pression atmospheric con aer secco como medio insulation externe. Distincte ab disenos sigillate con gas o a cielo aperte, iste architectura elimina totalmente le SF₆ dumque forni immunitate intrinsece contra umiditate, pollution e reduction pro altitudine per barriere dielectriche solide, plenamente schermate e connectite al terra.
The system employs standardized flexible busbar connectors that allow on-site reconfiguration of load-break switches, vacuum circuit breakers, and fuse-combination units without specialized tools or engineering redesign. Manufactured via automated casting lines with <5pC partial discharge consistency, each unit is validated for ≥30-year service life under IEC 62271-200, making it the definitive solution for decarbonization-mandated grid upgrades where footprint, safety, and lifecycle cost are equally critical.

Why Choose TSTY Solid Insulated Ring Main Unit?

All units feature touch-safe screened connectors, integrated earthing visualization, and optional digital sensor readiness for future-proof asset management.

Atmospheric-Pressure Solid Dielectric

Epoxy/silicone encapsulation operates at ambient pressure, eliminating gas monitoring, refilling, and end-of-life disposal liabilities; inherently immune to altitude derating up to 4,000 m without design modification.

Field-Reconfigurable Flexible Busbars

Standardizati busbar interfaci plug-in permittunt additio/remotio modularum functionum in loco in minus quam 2 horis per cellam; nullum soldari, nullum bullire, nullum testare dielectricum necesse est dum amplificatur.

Inherent Environmental Immunity

Moduli primari plene fusili attingunt protectionem internam IP67 independentem ab incloso; probati sunt pro corrosione C5-M, pro cyclis thermalibus -40°C/+85°C, et pro operatione continua ad 95% RH sine calefactoribus condensationis.

Automated Casting Consistency

Injectio robotica epoxidis certificat gradum descensus partialis (PD) minus quam 5pC in omnibus modulis; alliniamen interlock mechanicum verificatur in-fixture ante solidificationem, garantens repetibilitatem dimensionalem ±0.2mm trans omnes series productionis.

Optimisatio Custus Cycli Vitae

Zero scheduled maintenance over 30-year design life; no consumable seals, lubricants, or gas handling equipment required; total cost of ownership 35% lower than SF₆ RMUs over 25-year horizon.

Engineering & Global Compliance

Every TSTY Solid Insulated RMU undergoes rigorous validation aligned with international standards:

Examinatio Integritatis Isolationis Solidae

Each cast module undergoes individual PD measurement (<5pC @ 1.2Ur) and power-frequency withstand (42kV/1min); batch lightning impulse tests (75kV peak) confirm insulation coordination per IEC 62271-200.

Confirmatio Interfaciei Flexibilis Busbar

Insertion/extraction cycle testing (≥1,000 mates) verifies contact resistance stability (<50μΩ); thermal rise tests at rated current confirm joint performance under continuous load.

Verificatio Interbloccationis Mechanicae

Five-prevention interlock sequences tested under fault-make conditions; earthing switch short-circuit making capacity validated per IEC 62271-102 to ensure operator safety during energized access.

Simulatio Aetatis Ambientalis

3,000 h salt fog + UV exposure on assembled units confirms surface tracking resistance; thermal shock cycling validates epoxy-silicone interface adhesion over 30-year equivalent aging.
