A raceway aligns conduit disposed in one or more raceway segments. The conduit provides a pathway for one or more resources to be delivered to certain equipment at a site. An access port of the raceway segment provides access to the resources distributed or conveyed by the conduit. The raceway segments are anchored to a surface to provide stability. The raceway may also include a ground grid to ground the raceway or other equipment. The conduit may convey any number of resources required at the site. The resources may include utilities, fluid, communications lines, control lines, or any other resource needed at the site. Any number of raceway segments may be coupled together to form a raceway for a site.

An electronic circuit unit includes: a cable having a core of stranded thin wires, the core being covered with an outer surface, the outer surface at one end of the cable being removed to expose the core; a metallic tube that is tubular, the exposed core being inserted into an opening portion of the metallic tube; and a substrate including a connection land for connecting the core. The exposed core is connected to the connection land via the metallic tube by diffusion joining or ultrasound joining, the core has a diameter of 0.02 to 0.50 mm, the metallic tube has a thickness of 10 to 50 m, and the metallic tube has an inner diameter that is larger than the diameter of the core by equal to or more than 1.1-fold and equal to or less than by 1.5-fold.

An example assembly includes an electrically conductive member, an electrically conductive mesh, and a crimp connector. The electrically conductive mesh includes a first area and a second area. The second area extends along a second longitudinal axis and is larger than the first area. The first area is twisted and extends from the second area along a first longitudinal axis that is transverse to the second longitudinal axis. One of the electrically conductive member and the twisted first area is twisted around the other of the electrically conductive member and the twisted first area to form a twisted connection. The crimp connector is crimped onto the twisted connection to form a crimped connection. The first area of the electrically conductive mesh, including the crimped connection, is folded onto the second area of the electrically conductive mesh.
