Thermal insulation of cable fireproof tray

QINKAI cable tray discloses a cable fireproof tray, which adopts the outer flame retardant and inner multi-layer thermal insulation, and is equipped with ventilation and rain-proof components, which makes the fire protection function more perfect and has excellent effect. This type of QIKAI frame is formed by bending steel plate into a steel structure. Its exterior is coated with fireproof paint, and its interior is covered with asbestos felt plate. It is also equipped with heat insulation board, anti-radiation board, shutter and rain-proof cover, which are placed on the upper part of the shaped steel structure. There are jumper sleeves and X-shaped jumper wires between adjacent units of the QINKAI tray. In case of fire, when the tray is in flame, the temperature of the cable contact surface placed in the center of the cable tray of Qinkai is maintained at 60~70C due to the use of multi-layer insulation and good ventilation heat conduction.

A cable fireproof qinkai cable tray is made of steel trough box, inner insulation material and cable clamp. It is characterized in that its steel structure tray body is made of cold rolled steel plate into a long strip, its section is U-shaped, its outer side is coated with fireproof coating, the U-shaped inner side is covered with asbestos felt plate, the radiation reduction plate is also a long strip, its section is door-shaped, and it is placed on the insulating asbestos drill plate, The heat insulation panel with the same plane size as the radiation reduction plate shall be used for covering. The upper part of the U-shaped qinkai tray body shall be covered with rain-proof, ventilation cover and tray cover: connecting wires shall be provided between adjacent units, and a pair of jumper bolts shall be provided at the beginning and end of each unit.

QINKAI cable tray perforated cable tray is a device for laying cables, which is used to erect and protect cables and extend the service life of cables. QINKAI cable tray perforated tray is composed of two ladder edges, several steps and rivets through riveting. The cover plate is covered at the upper end of the ladder edge. The tray and tray are connected by bolts through the inner direct plate, ladder edge, outer direct plate, washers and nuts.

The qinkai cable tray perforated cable tray belongs to a cable laying device. The utility model is characterized in that it is riveted and the cover plate is covered at the upper end of the ladder edge to form a through-hole bracket. The cable ladder and cable ladder are connected by bolts through the longitudinal oblong hole on the inner direct plate, the transverse oblong hole on the ladder edge, the longitudinal oblong hole and the heat ring on the outer direct plate, and the nuts are fastened. The through-hole tray is supported by angle bar or wall support and C channel .
