Precision Engineering. Powering Industrial Reliability.
PT. Prastiwahyu Tunas Engineering designs, manufactures, and commissions medium- and low-voltage switchgear, LVMDP boards, STAR-E IEC 61439 type-tested systems, and commercial EV fast chargers for mission-critical industries, public transit, and data centers.
PT. Prastiwahyu Tunas Engineering designs, manufactures, and commissions type-tested low-voltage switchboards, medium-voltage switchgear, and commercial EV fast charging solutions. From mass transit rail networks and hyperscale data centers to industrial oil & gas facilities, PTE delivers precision-engineered switchgear built to IEC 61439 standards, setting the benchmark for electrical safety and continuous uptime.
Proven Reliability. International Quality Standards.
Four engineering pillars embedded in every project, from concept engineering and CAD modeling through factory acceptance testing and field commissioning.
Bankable hardware, Tier-1 components
Authorized licensed partnership with leading global electrical manufacturers: Schneider Electric, ABB, Siemens, and Chint.
Type-Tested Switchboard Manufacturing, Contracted
Modern manufacturing facilities in Jababeka Industrial Estate Phase II equipped with CNC fiber laser cutting, precision robotic press brakes, and automated busbar fabrication.
Indonesian Manufacturing, TKDN & ISO Certified
100% engineered and assembled in Indonesia with certified TKDN local content and verified IEC 61439 type-test credentials.
Fault-Tolerant Architecture, Arc-Resistant
Full Form 4b compartment segregation and 99.9% pure electrolytic copper busbars engineered for complete operator safety and thermal resilience.
“In mission-critical infrastructure, electrical distribution is the vital lifeline where failure is never an option. PT. Prastiwahyu Tunas Engineering designs and manufactures certified type-tested switchboard systems and MV switchgear that safeguard Indonesia’s transit corridors, hyperscale data centers, and heavy processing facilities with unconditional reliability.”
“True engineering reliability cannot be simulated—it must be proven and validated on the factory floor. At our modern Jababeka manufacturing plant, every STAR-E, VOLT-E, and partner assembly undergoes full primary injection FAT testing up to 6300A under strict IEC 61439-1 & 2 standards, uniting international certifications with high domestic content (TKDN).”
“As Indonesia accelerates toward commercial fleet electrification and modern clean energy networks, our electrical infrastructure requires unprecedented resilience. Prastiwahyu is actively delivering this future—deploying commercial ultra-fast DC EV chargers (SPKLU), 24kV medium-voltage switchgear, and turnkey O&M diagnostics across the archipelago.”
