Price of low-voltage enclosed busbar trunking in Singapore

Low-voltage enclosed busbar trunking systems in Singapore typically range from SGD 150 to SGD 600 per meter, depending on current rating, conductor material, and system configuration.

Overview

Low-voltage busbar trunking systems, such as the Tai Sin LT Line I, are designed for flexible and efficient power distribution in commercial, industrial, and data center applications. These systems support configurations like 3P3W, 3P4W, and 3P5W, with rated currents from 250A to 4000A for aluminum conductors and 400A to 5000A for copper conductors, and operation voltages up to 690V with insulation rated up to 1000V. They are built with sandwich construction, offering high electrical efficiency, low voltage drop, and mechanical robustness, with IP ratings up to IP66 for protection against dust and water ingress .

Factors Affecting Price

1. Conductor Material: Copper busbars are generally more expensive than aluminum due to higher conductivity and material cost.
2. Rated Current: Higher amperage systems require larger busbars and insulation, increasing cost.
3. System Length and Accessories: Prices vary with straight lengths, elbows, tees, tap-off units, and expansion joints.
4. IP Rating and Insulation Type: Systems with higher IP ratings or epoxy insulation options are priced higher.
5. Supplier and Certification: Locally tested and certified systems (e.g., IEC 61439-6, KEMA KEUR) may carry a premium .

Typical Price Range

• Aluminum conductor systems: SGD 150–350 per meter for 250A–1000A, SGD 350–500 per meter for 1000A–4000A.
• Copper conductor systems: SGD 300–450 per meter for 400A–1000A, SGD 450–600 per meter for 1000A–5000A. These prices are indicative and can vary based on project volume, customization, and supplier discounts. For precise pricing, it is recommended to request a quotation from local suppliers such as Tai Sin Electric or Schneider Electric Singapore, which provide detailed price lists and project-specific estimates .

Conclusion

Low-voltage enclosed busbar trunking systems in Singapore are a reliable and flexible solution for high-efficiency power distribution. While typical prices range from SGD 150 to SGD 600 per meter, the final cost depends on current rating, conductor type, system configuration, and accessories. Contacting suppliers directly ensures accurate pricing tailored to your project requirements.
