TAIAN-ECOBAR TECHNOLOGY

TAIAN-ECOBAR TECHNOLOGY was formally called TAIAN Electric Co., Ltd.(TECO GROUP). With the drastic increase in the requirement of safety and stability for power distribution, the traditional power cable and metal-enclosure busway can no longer fulfill the requirement from customers. Therefore, the cast resin insulated busway TECOBAR is the best solution in order to meet the requirement. To provide the safest and most reliable power systems to the world is our commitment. Thus, your precious comments and supports are the most incentive to us.

Copper, NLV Series

TAIAN-ECOBAR TECHNOLOGY designs and manufactures Copper that complies with the most stringent operating requirements. Our Copper is energy-saving, high efficiency, environment-friendly, and attractive, because we strictly control quality throughout the manufacturing process.

NLV Series

Copper

TECOBAR Low Voltage Cast-Resin Insulated Busway is developed for electrical systems below 1kV.

The product has features of safety and compact. It is designed to use the insulation material to perform cast resin sealing to the copper (aluminium) conductor. The insulation material is cast resin which contains non-organic volcanic rock with the features of excellent insulation characteristics, mechanical strengh, humidity-proof, non-combustible, and self-extinguishing .
