Flame Proof Enclosures TNDLDE (Line Bushing for Ex-d to Ex-e Compartments)
Application: The TNDLDE range of line bushing are
designed as components for use in all Ex de enclosures to
pass connection between the Ex d and Ex e compartment
in combination Ex de enclosures. The TNDLDE is designed
to accommodate coaxial cables such as RG179 (50?) or can
be manufactured to order for custom or hybrid bushing
requirement.
