LADDER TYPE CABLE TRAYS
3E Solutions is one of the leading ladder type cable tray manufacturer in Jaipur, Rajasthan. Generally used in applications with intermediate to long support spans 12 to 30 feet. A ladder cable tray without covers permits the maximum free flow of air across the cables which allows the heat produced in the cable’s conductors to effectively dissipate. Under such conditions, the conductor insulation in the cables of a properly designed cable tray wiring system will not exceed its maximum operating temperature.
Construction of Ladder type cable trays
The rungs of the ladder cable trays provide convenient anchors tying down the cables in the non-horizontal cable tray runs or where the positions of the cables must be maintained in the horizontal cable tray runs. Generally this capability is a must for single conductor cable installations. Under fault conditions (short circuit), the magnetic forces produced by the fault current will force the single conductor cables from the cable tray if they are not securely anchored to the cable tray.
Cables may exit or enter the ladder cable trays through the top or the bottom of the cable tray where the cables enter or exit conduit, the conduit to cable tray clamps may be installed upright or inverted to terminate conduits on the top or bottom of the cable tray side rail. The most common rung spacing for ladder cable tray is 9 inches. This spacing may be used to support all sizes of cables.
