Tampereen Sähköpalvelu

What Tampereen Sähköpalvelu does

Tampereen Sähköpalvelu Oy (TSP) is a Finnish B2B distributor and importer of electrical components and accessories, founded in 1968 and headquartered in Pirkkala, with a manufacturing facility in Turku. The company organizes its offering into nine product categories: connectors and harness materials; industrial cables; tools and production technology; panel and installation products; network and data center cabling; measurement, testing, and quality assurance; Intertrafo-branded transformers and power supplies; GE Tetra LED signage products; and clearance inventory. The Turku production unit manufactures the proprietary Intertrafo line (interCUSTOM, interAUDIO, interCONTROL, interSAFETY, interISOLATE, interMARINE, interMED, interFILTER), including the only Finnish-made audio and line transformers and UL/IEC-certified designs for international OEM customers.

The business model combines physical-product distribution with light custom manufacturing and recurring services. Revenue is generated through per-unit hardware sales (pieces, meters, rolls), quote-based pricing for custom transformers, and multi-year maintenance contracts on represented production equipment, supported by product/system training and warehouse storage services. The go-to-market is sales-led, B2B account-based, targeting Finnish industrial companies, OEMs, and electrical installation professionals through field sales, phone/email/chat support, an account-gated e-commerce storefront, and a pickup showroom in Pirkkala. Same-day dispatch from a large in-house warehouse is a core operational promise.

TSP is a wholly-owned subsidiary of Addtech, a Nordic-Baltic technical trading conglomerate of approximately 150 independent subsidiaries, and operates with group-level resources while retaining operational autonomy.
