What Sintra does

PT. Sintra Sinarindo Elektrik (SINTRA), founded in October 1996 in Lippo Cikarang, West Java, is an Indonesian designer, manufacturer, and tester of electrical transformers. Through its wholly-owned subsidiary PT. Sintra Power Elektrik (established July 2013), the company operates two adjacent production facilities in the Lippo Cikarang industrial hub and a sales and marketing office in Central Jakarta. SINTRA's product portfolio spans oil-immersed distribution transformers (single-phase and three-phase, up to 20MVA and 33kV), high-voltage power transformers (up to 150MVA and 150kV), cast-resin dry-type transformers, and SF6 gas-insulated pole-mounted Load Break Switches (up to 24kV), supplemented by maintenance, repair, and refurbishment services.

SINTRA's technical differentiation rests on vertically integrated manufacturing with in-house 150kV testing capabilities, Vapor Phase Drying (VPD) for insulation moisture removal, and advanced design simulation using CFD and FEA tools. The company holds ISO 9001, ISO 14001, SMK3, KEMA (now DNV), and SPLN T3.007:2016/2017 certifications, and reports TKDN (local content) compliance of 48.8% as required for PLN suppliers. A 2021 partnership with Cargill Indonesia enables production of FR3 bio-based natural-ester fluid transformers that materially reduce fire risk, a feature that has become a key export differentiator.

SINTRA generates revenue primarily through one-time sales of custom-engineered transformers, quoted per specification and delivered through a direct enterprise field-sales motion. Its customer base is anchored by Indonesia's state-owned utility PT PLN (Persero) and PLN Pembangkitan, and extends across oil and gas (Pertamina Hulu Rokan, Chevron Pacific Indonesia), heavy industry (Riau Andalan/APRIL pulp and paper, Indak Kiat, Semen Indonesia, Krakatau Daya Listrik, Mulia Adhitama Sejati), manufacturing (Maxxis, TIFICO, Indo-Bharat Rayon, Muliakeramik Indahraya), and EPC contractors. Recurring revenue is augmented through maintenance contracts and transformer refurbishment partnerships such as the 2023 Serba Dinamik alliance. In May 2024, SINTRA added an export channel via a strategic partnership with TECO-Westinghouse USA to supply FR3-filled power transformers into North America, marking its first major geographic expansion beyond Indonesia.

Broad incumbents

• ABB: Global Swiss-Swedish electrical-equipment major with a long-standing power-transformer portfolio. Listed on SINTRA's own customer logo wall as an EPC partner; competes directly for large utility and industrial transformer contracts in Indonesia.
• Schneider Electric: Global electrical-equipment major offering distribution transformers and switchgear integrated with broader energy-management solutions. Overlaps with SINTRA's cast-resin, distribution, and industrial-customer base.
• Hitachi Energy: Former ABB Power Grids; one of the world's largest transformer manufacturers with full coverage from distribution to large power transformers. Direct competitor in PLN tenders and ASEAN industrial projects.
• Siemens Energy: Global energy-technology major with a substantial transformer manufacturing business (including large power transformers). Also appears as a customer/EPC on SINTRA's website, and competes in Indonesian utility and industrial tenders.
• GE Vernova (Prolec GE): GE's energy business including Prolec, a major transformer manufacturer for utility and industrial customers in the Americas. Competes for similar utility-scale power-transformer contracts as SINTRA, particularly in the 60-150MVA range.
• Eaton: U.S. power-management major with a transformer and switchgear portfolio serving utilities and industrial customers globally. Overlaps with SINTRA's distribution-transformer and LBS/SF6 switch offerings in industrial segments.

Regional players

• Wilson Power Solutions: UK/Australia-focused power and distribution transformer manufacturer. Comparable in scope (mid-size transformers, custom engineering), though primarily serving UK/Australia rather than Indonesia.

Direct peers

• PT UNINDO: Another established Indonesian transformer manufacturer, including power and distribution units. Operates in the same domestic PLN-supplier ecosystem and competes for Indonesian utility contracts.
• TECO-Westinghouse: U.S.-based manufacturer of motors, generators, drives, and power transformers; current strategic distribution partner of SINTRA for North American FR3-oil transformer exports. Same product category (power transformers), similar voltage class, and direct strategic overlap.
• PT Bhakti Surya Persada: Indonesian transformer and electrical-equipment manufacturer serving PLN and industrial customers. Domestic peer competing for the same Indonesia utility and industrial transformer tenders.
