Direct access to high-purity electrical conductor winding solutions certified to meet the demanding load conditions of distribution systems across Indonesia.
As Indonesia pushes forward with the RUPTL (Electricity Supply Business Plan), Jakarta’s metropolitan zone and its surrounding industrial satellites (Bekasi, Cikarang, Karawang) are undergoing massive power infrastructure upgrades. The transition towards high-voltage distribution networks requires transformers constructed with high-grade Paper Covered Flat Wire to prevent localized thermal degradation and short circuits under heavy tropical loads.
Jakarta’s climate presents unique challenges. With relative humidity regularly peaking at 90%, raw transformer winding insulation must boast impeccable dielectric strength and moisture resistance. Our range of paper-insulated rectangular copper and aluminum wires utilizes premium thermally upgraded kraft paper and Nomex wrapping, maintaining a low dissipation factor and preventing dielectric breakdown in high-condensation environments.
State-owned utility provider PLN (Perusahaan Listrik Negara) enforces stringent component standards. Transformers destined for local grids require windings that offer minimal resistance and superior space factors. Flat rectangular profile wires allow for highly compact coils, decreasing winding window size while increasing overall transformer efficiency—vital for space-constrained substation rebuilds inside urban Jakarta.
Selecting the right winding material directly affects the lifecycle, weight, and copper/aluminum losses of power transformers. Modern industrial systems require rigorous attention to insulation layers, dimensional tolerances, and electrical resistivity parameters.

Operating out of our advanced industrial facility, we maintain vertical control over metallization, drawing, extrusion, and wrapping processes to supply the most demanding infrastructure projects in Jakarta.
With a plant footprint covering over 258,333 sq. ft., we utilize high-precision continuous extrusion (Conform) machines and multi-layer wrapping installations to guarantee zero-defect production outputs.
Our flat rectangular wire products feature micro-precision corner radii (R) compliant with international norms. This prevents electrical field concentrations at sharp edges, significantly reducing the risk of localized dielectric breakdowns.
Serving over 10 cooperating nations, we coordinate seamless maritime logistics directly to the Tanjung Priok Port in North Jakarta, ensuring timely distribution to electrical equipment factories across West Java.
Every winding profile receives continuous-feed paper wrapping with strictly controlled overlap tension. This ensures no peeling, displacement, or air gaps within the insulation layers, even during tight automatic coil-winding operations.
Designed for severe duty cycles, our magnet wires demonstrate robust resistance against structural softening and mechanical compression under load, preserving transformer integrity during system faults or spikes.
Optimizing wire cross-sections helps reduce standard load losses. In municipal networks and commercial high-rises in Jakarta, choosing high-conductivity flat wires helps operators lower operational costs and meet green emissions mandates.
Our insulated magnet wires perform at the heart of systems driving Indonesia’s commercial growth and heavy industrial sectors.
Used extensively in power transformers, distribution transformers, and substations where high-density energy conversion requires consistent dielectric strength and reliable thermal dissipation.
Supplying robust winding wire to heavy industrial motors, backup generators, and propulsion systems, maintaining mechanical integrity under constant rotational vibrations.
