KINTO is the leading supplier in China for manufacturing of flexible insulated busbars. Such busbars consist of several layers of uncoated or tinned copper strips and are insulated with flexible high quality PVC compound.
The main features of flexible insulated busbars:
– Easy assembly.
– Possibility of reducing sizes of the equipment.
– The bending-radius could be smaller than that of normal cable or solid copper bars, so that the connections could be more simple and short, and visually it could have better effect.
– Lower temperature rise on the flexible insulated busbars than on normal copper bars.
– High flexibility: no problem with vibrations or thermal expansions.
