Product design and prospect

WTI devotes itself to develop the most advanced technology in busway industry. WTI insists on yielding the highest quality and level of products and provides high-grade service to our honorable customers.
WTI has technical cooperation with Belgium比利時王國,通稱比利時,西歐國家,為歐洲聯盟的創始會員國之一。其首都布魯塞爾是歐盟與北大西洋公約組織等大型國際組織的總部所在地。比利時自北起順時針分別與荷蘭、德國、盧森堡和法國接壤,西面則濱臨北海。比利時的名稱,源自羅馬時代,當時此地稱為比利時高盧,字面意為貝爾蓋人的高盧。 to surmount mold cast technology in busway industry. WTI upgrades the mold cast busway by researching and developing ore type busway innovatively so that mold cast busway can be applied to various projects safely. From indoor to outdoor, from data center and semi-conductor factory to petrochemical and biotechnology factories, and even the hospital and the airport which are most relevant to personal safety, only by passing the harshest environment test can our customers feel at ease and attentive.

Joint research and development with European mold cast authority and innovative ore insulation technology among the industry makes impossibility possible.

Ore heat-resistant technology

Having mold cast materials generate chemical change in the flame to extinguish the flame effectively meets the domestic and foreign standard and certification such as CNS、IEC、BS.

Ore cooling technology

WTI busways achieve energy saving efficacy and obtain green mark by reducing temperature of conductor effectively, improving the thermal resistance of conductor at high temperature and decreasing the loss of busways.

Ore weather resistance technology

Ore weather resistance technology improves the weather resistance level significantly in the mold cast industry which makes the outdoor busway not a nightmare anymore and far away from mold cast materials cracking and overheats cracking.

Ambient mold cast technology

From the straight feeders and elbows to joints on site, mold cast technology at ambient can protect the conductor thoroughly and ensure the product to meet IP68.

Formulated by high voltage mold cast

WTI upgrades the level of voltage withstand for mold cast up to 50% greatly and has integral series of high and low voltage products that makes WTI can provide the complete solutions to satisfy all needs be met at one time. WTI has the optimal structure design to strengthen the intensity of product structure so that the maintenance is free and product life is more than 50 years.

Our path of R&D won’t stop due to have been satisfied and we’ll keep improving the product, new design and the manufactural procedure. We’ll continue to innovate and welcome our partners and customers to give us suggestions and work with us to build up more perfect power product and create safe and reliable power quality.
