Distribution boxes, cable tray vertical shaft, trough cable tray, tray cable tray, Ladder type cable tray, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable trays, stainless steel cable tray, aluminum alloy cable tray, room alignment bridge, FRP cable tray, CSP alloy plastic cable tray, cable tray installation - Henan InfoQuick bridge voltage electrical equipment Co. cable on cable tray level arrangement: 1, cable tray arrangement should be weak level Current control cables on top, followed by the general control cables, low voltage power cables, high-voltage power cables turn down the row. This arrangement is conducive to shield interference with the power cable cooling CSP alloy plastic cable tray, to facilitate the construction. 2, the distance between layers of cable tray layer as follows: Control cables Power cables ≥ 200 mm ≥ 300 mm ≥ 400 mm mechanized laying cable distribution boxes, shafts cable tray, trough cable tray, tray cable tray, cable tray stepped CSP Alloy plastic cable tray manufacturers, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable trays, stainless steel cable tray, cable tray CSP aluminum alloy plastic cable tray pictures, room alignment tray, FRP cable bridge, CSP CSP alloy plastic alloy plastic cable tray cable tray production, cable tray installation - Henan InfoQuick bridge when electrical equipment Co., Ltd. cable tray wiring (1) the use of cable tray wiring in the room, its cable should not have jute or other easily retardant outer sheath material. (2) When there is corrosion or humid place using special cable tray routing, should take appropriate protective measures differ according to the corrosive medium, and should use plastic-sheathed cable. (3) Cable tray (tray) height from ground level when installed in general should not be less than 2.50m, 1.80m following section should be added to the metal cover to protect from the ground when mounted vertically, but laying in the electrical rooms (such as distribution ) except when the chamber within the electrical shaft, technology layer. (4) horizontal cable tray installation, according to the load curve should be supported to select the best span, the span is generally 1.5 ~ 3m. Vertical laying, fixed point spacing should be less than 2m. (5) sets of cable tray is installed in the same highly parallel between each adjacent cable tray should consider maintenance, overhaul distance. (6) on the cable tray spacing can be no laying of cables, cable tray cross-section in the filling factor: power cables should not exceed 40%; control cables should not exceed 50%. (7) The following different voltages, different uses of the cable, not laying on the same floor bridge: [CSP] alloy plastic cable tray, CSP alloy plastic cable tray manufacturers, InfoQuick provided by InfoQuick bridge electrical equipment.
