摘要： A fire-resistive cable system comprises an electrical cable housed in a fiberglass-reinforced thermosetting resin conduit. The electrical cable comprises a conductor and has only one couple of mica tapes surrounding the conductor. The couple of mica tapes are formed of a first mica tape and a second mica tape wound around the first mica tape. The mica layer of the first mica tape faces and contacts the mica layer of the second mica tape. The fiberglass-reinforced thermosetting resin conduit is made of a material comprising fibers of a glass selected from E-glass and E-CR-glass, and a resin.

摘要： The present invention provides an electromagnetic wave-permeable brilliant coated resin product which has a brilliant coating film formed by applying a coating composition that includes a planar brightening material formed from aluminum, on a resin substrate. Within the brilliant coating film, the brightening material is oriented in a state such that a plane thereof is biased toward a direction that follows a surface of the brilliant coating film, and an average overlapping quantity (y), which is an average of a quantity of brightening material that crosses one orthogonal line that is orthogonal to the surface of the brilliant coating film, and an average inter-brightening material distance (x), which is an average of distances on the orthogonal line between adjacent brightening materials that cross said orthogonal line, satisfy the following two formulae: y≧0.5 (formula 1), and y≦0.3969x+0.594 (formula 2), where, the unit for x is μm.
