Engineered around cold-rolled grain-oriented (CRGO) steel, high-permeability MnZn ferrite cores, and robust thermal isolation to satisfy Tetovo’s emerging commercial infrastructure.
Ultra-compact AC/DC wall adapter incorporating high-density flyback ferrite cores, offering broad compatibility for low-power telecom modules, instrumentation benches, and municipal security systems.
Fully potted polyurethane-sealed transformer enclosure engineered for high-altitude mountainous Balkan climates, shielding internal toroidal windings from moisture and aggressive condensation cycles.
Built with interleaved planar transformer coils to optimize heat dissipation, providing precise constant-current charging for micro-mobility fleets operating across urban Tetovo distribution links.
Chassis-mount industrial SMPS integrating low-loss silicon steel power cores designed to withstand rugged fluctuating grid loads across Polog Valley manufacturing plants.
Equipped with low-hum toroidal isolation filtering and active PFC, this 600W unit supplies ripple-free direct current to commercial architectural illumination and CNC controllers.
Class-H insulated low-profile transformer built for linear integration within building automation raceways, architectural LED installations, and high-bay commercial retrofits.
Engineered around premium ferrite PQ cores to maintain conversion efficiency above 91%, substantially reducing electrical thermal footprints in enclosed industrial automated panels.
Standard TS-35 rail mounting power unit designed for SCADA cabinets, elevator control nodes, and perimeter surveillance hubs requiring unconditional galvanic mains isolation.
Within the Tetovo industrial basin, the intersection of legacy grid distribution lines and heavy modern manufacturing yields intermittent harmonic distortion, low power factor conditions, and unexpected thermal spikes. The foundational bottleneck in system survival is neither the external casing nor secondary terminal blocks—it is the metallurgical integrity of the transformer core.
Shaanxi Zelqo Power manufactures transformer magnetic cores fabricated from high-grade, laser-scribed Grain-Oriented Silicon Steel (CRGO) such as 23Q110 and 27Q120, along with high-permeability Manganese-Zinc (MnZn) ferrite materials. By strictly controlling the magnetic flux density ($B_m$) within 1.6 to 1.75 Tesla for 50Hz grid setups, our engineering avoids saturation knee-points during line transient overvoltages common in North Macedonia’s mountain-valley topography.
Our vacuum-impregnated epoxy encapsulation processes mitigate core mechanical vibrations, cutting acoustic humming below 38 dB(A)—imperative for modern municipal facilities, universities like the State University of Tetova, and regional health centers where quiet operation is legislatively enforced.
From modern wood processing and textile automation along the Skopje-Tetovo highway to renewable mountain hydro plants, Zelqo magnetic assemblies solve critical power conversion challenges.
Textile mills, automotive parts workshops, and precision furniture manufacturing lines in Tetovo require clean, noise-free 24VDC and 48VDC rails. Our low-leakage EI and toroidal power cores block common-mode electrical noise, preventing expensive logic faults in PLCs and high-speed robotic servo drives.
With residential expansion accelerating toward the Šar Mountains, multi-tap elevator auto-transformers and DIN-rail DC supplies ensure resilient vertical transportation. Built-in thermal cutoffs and Class H (180°C) wire insulation guarantee fail-safe mechanical brake actuation and cabin levelling accuracy.
Small-scale hydro generation across the Pena River and expanding commercial rooftop photovoltaic arrays demand high-frequency step-up transformers with low iron-loss profiles. Our customized ferrite designs manage frequencies up to 250kHz, ensuring inversion efficiencies exceeding 98.4%.
North Macedonia's continuous harmonization with the European Union Energy Community frameworks has instituted strict mandates regarding electrical efficiency and harmonic pollution. Tetovo, being the epicenter of the country's Western economic corridor, is transitioning rapidly away from outdated, high-loss oil-immersed cores toward dry-type toroidal and high-permeability strip-wound cores.
Local industrial procurement leads no longer purchase baseline off-the-shelf transformers. The standard is now defined by lifecycle total cost of ownership (TCO). A transformer core operating at 92% efficiency versus our optimized 97.8% system saves local commercial facilities tens of thousands of Euros over operational lifespans, dampening grid instability while meeting the stringent Tier 2 limits of EU Regulation 548/2014 for ecodesign transformers.
Furthermore, as cross-border transport routes toward Albania and Kosovo broaden via the Corridor VIII infrastructure projects, Tetovo is becoming an assembly and staging capital. Supplying certified, Intertek-verified magnetic components allows local assemblers to export finished electromechanical gear seamlessly into the broader European Common Market.
Shaanxi Zelqo Power Co., Ltd. operates advanced automated coil winding, precision cutting, and automated multi-stage inspection facilities in Xi'an, offering turnkey B2B procurement confidence.
Our production facilities, supply chains, and technical capabilities undergo comprehensive on-site audits, ensuring Western Balkan buyers procure genuine direct-from-manufacturer components without intermediaries.
We build precisely to customer schematics or calculate bespoke turns, air gaps, potting configurations, and terminal footprints to match tight control enclosures and European EN 61558-1 standards.
Every single manufactured unit is scrutinized via LCR bridge analyzers, impulse winding testers, primary-to-secondary breakdown testers, and digital AC power meters before sea or air dispatch.
