Verification of Temperature Rise Limit
The following pictures illustrate some temperature rise tests successfully carried out on Furutec busduct system.
Furutec Busduct System is capable of carrying full rated current continuously in ambient condition of 95% relative humidity and
maximum ambient temperature of 40 o C. When busduct is installed in a higher ambient temperature, the busduct current ratings
shall be derated according to the factors as illustrated in the table below.

Verification of Dielectric Properties
It comprises two tests, namely dielectric test voltage and impulse voltage withstand test. They are applied to all live parts and
interconnected exposed conductive parts of the busduct system.
For the impulse voltage withstand test, the busduct is tested with a test voltage of 7.4kVpk. The 1.2/50µs impulse voltage applied
3 times at the interval of 1s minimum.
For the dielectric test voltage, it is carried out after the type tests, such as temperature rise test, short circuit strength test, degree
of protection test, structural strength test, crushing resistance test, etc in order to ensure that no electricity current leaking occurs.
