I. Instructions for the model compilation of epoxy resin and epoxy resin composite cable trays:
The model compilation of epoxy resin and epoxy resin composite cable trays is divided by structure:
1. Trough type (C) 2. Ladder type (T) 3. Tray type (P)
II. Selection of the specifications of epoxy resin and epoxy resin composite cable trays:
The cable filling rate shall not exceed the standard specified value. For power cables, it can be 40 - 50%, and for control cables, it can be 50 - 70%. In addition, a 10 - 25% margin for project development shall be reserved. See the following table for the selection of the cross - sectional area of the cable tray. All bends and accessories shall meet the engineering layout conditions and be matched with the cable tray.
III. Selection of the load grade of epoxy resin and epoxy resin composite cable trays:
In addition to its own weight, the cable tray shall also include the mechanical load of the wires and cables it can bear. The working uniform load shall not be greater than the rated uniform load of the selected load grade. When the cable tray bears the rated uniform load, its
relative deflection of epoxy resin and epoxy resin composite should not be greater than 1/200. Material Support and hanger span mm Rated uniform load N / m Deflection value (not greater than) mm Side height 100mm Side height 150mm Side height 200mm Epoxy resin composite 2000
1000 1850 3100 10 The strength of the load of epoxy resin and epoxy resin composite cable trays is related to the reliability and durability of the structure and is an important basis for structural design. In actual use, in addition to the cable load and self - weight, the following loads should also be considered:
1. For cable trays installed outdoors, the loads of wind, rain or ice should be considered. For earthquake - prone areas, inertial loads should also be considered.
2. In addition to bearing normal mechanical loads, cable trays should not be used as pedestrian passages in principle. If it is necessary to use it as a pedestrian passage or for other purposes, special design for this purpose should be negotiated with the user.
3. In the load design of cable trays, not only vertical loads but also longitudinal and transverse loads existing during the installation and use process should be considered (such as the longitudinal traction force generated when laying cables and the transverse load generated when a ladder leans against the cable tray)
IV. Configuration of supports and hangers for epoxy resin and epoxy resin composite cable trays:
1. The short span of indoor supports and hangers is generally 1.5 - 3m. The span of outdoor columns is generally 6m.
2. The configuration of supports and hangers for non - straight sections should follow the following principles: When the width W of the cable tray is less than 300mm, a support or hanger should be installed on the straight - section side 300 - 600mm from the junction of the non - straight section and the straight section; when the width w of the cable tray is greater than 300mm, in addition to meeting the above conditions, an additional support or hanger should be added in the middle of the non - straight section.
3. When the cable trays are arranged in multiple layers, the center - to - center distance between layers is 200, 250, 300, 350mm.
5. Technical requirements for epoxy resin and epoxy resin composite cable trays:
The structural design is reasonable, with the advantages of advanced technology, beautiful appearance, smooth surface, uniform thickness, high mechanical strength, convenient installation, corrosion resistance and aging resistance. The material of the cable tray is epoxy resin composite, with a metal skeleton inside. The shape of the metal skeleton is the same as the cross - section of the cable tray, and the material is cold - rolled steel plate with a thickness of 1.5 - 2.0mm (150 ≤ B ≤ 300: 1.5mm, 400 ≤ B ≤ 800: 2.0mm). The metal surface should be specially treated, and a soft bonding layer should be added to prevent the metal skeleton from delaminating from the main anti - corrosion layer due to different thermal expansion coefficients. The cable tray has a main anti - corrosion layer outside the metal skeleton. The average thickness of the anti - corrosion layer is 1.5mm - 2.0mm, and the specific gravity is 1.7 - 2.0g/cm3. There must be a protective layer with high density, damage resistance and the function of reflecting ultraviolet rays outside the main anti - corrosion layer. The surface is smooth and beautiful to improve the aging performance and service life of the cable tray. The inner lining fiberglass cloth is woven from three - free (alkali - free, wax - free, twist - free) glass fibers. The filler uses light - weight aluminum hydroxide to reduce its own weight, thereby improving the bearing capacity of the cable tray. Any end face, connection face and connection hole of the cable tray should have measures to prevent strong corrosion and strong external force. It is required that the main anti - corrosion layer, bonding layer and protective layer be formed by hydraulic pressing at one time. It has strong anti - corrosion ability, and can have a service life of 30 years in harsh environments such as acids, alkalis, salts and ammonia without aging or fading. The flame - retardant oxygen index of the cable tray is not less than 30%. Stainless steel bolts are used for connection.
