Extruded plastics conduit for electricity cables and liquid - consists of rectangular cross=section body with different dia. circular passages

摘要

The conduit is made of extruded plastics and has a flat cross-section in which are a number of parallel ducts with circular cross-section and with different diameters. The ducts of the same diameter are arranged symmetrically in relation to the lengthwise axis of the conduit. The parts of the conduit situated between the ducts constitute relieving arches for transmitting the force applied to the top of the conduit to the middle. Those ducts for electricity cables are positioned between ducts for non-compressed fluids. Some of the ducts can contain a metal core which acts as a support for when the conduit is suspended between two points.
