Color of the BBT & BBT Plus is red. The BBT & BBT Plus provides excellent insulating properties and have good flexibility for installation on all types of bus bars. BBT is a medium wall bus bar tube for genaral applications and BBT Plus is a heavy wall bus bar tube for applications which require a higher level of insulation.
Typical
Applications
Busbars insulated with Ikebana BBT & BBT Plus are corona discharge free even with shorter spacing between phase to phase. This enables compact switch gear panel design. It offers good protection from environmental effects, ultra-violet radiation and moisture. The tough cross-linked polyolefin material provides good mechanical protection.
