Tray-type Cable Trays:
Tray-type cable trays are the most widely used variety in sectors such as petroleum, chemicals, electric power, light industry, broadcasting, and telecommunications. They offer advantages such as light weight, high load-bearing capacity, attractive appearance, simple structure, and ease of installation; they are suitable for installing both power cables and control cables.
Surface treatment options for tray-type cable trays include galvanizing, electrostatic powder coating, and hot-dip galvanizing, depending on user requirements; special anti-corrosion treatments are available for highly corrosive environments.
Covers are available for tray-type cable trays and can be specified at the time of ordering; all accessories are interchangeable with those used for ladder-type and trough-type cable trays.
Ladder-type Cable Trays:
The XQJ-T ladder-type cable tray was developed based on domestic and international technical data and improvements made to our factory's existing similar products. It features light weight, low cost, a unique design, ease of installation, and excellent heat dissipation and ventilation. It is suitable for laying cables with larger diameters, particularly high- and low-voltage power cables.
Covers are available for ladder-type cable trays and can be specified at the time of ordering; all accessories are interchangeable with those used for tray-type and trough-type cable trays.
Surface treatment options for ladder-type cable trays include electrostatic powder coating, galvanizing, and painting; special anti-corrosion treatments are available for highly corrosive environments.
Trough-type Cable Trays:
Trough-type cable trays are fully enclosed units. They are ideally suited for laying computer cables, communication cables, thermocouple cables, and control cables for other highly sensitive systems. They provide effective shielding against interference for control cables and offer superior cable protection in highly corrosive environments.
Covers for trough-type cable trays are supplied together with the trough body, while other accessories are interchangeable with those used for ladder-type and tray-type cable trays. Users requiring other specifications or types of trough-type cable trays may place orders by submitting drawings, sending inquiries, or discussing requirements in person. Modular Cable Trays:
Modular cable trays represent the latest generation of cable tray products. Suitable for a wide range of engineering projects and cable laying applications, they feature a simple structure, flexible configuration, convenient installation, and an innovative design.
By utilizing just three basic widths-100mm, 150mm, and 200mm-these trays can be assembled into any required size. They allow for arbitrary changes in direction, width, and branching (including vertical transitions) to meet on-site installation needs without requiring specialized fittings like elbows or tees. Conduit connections can be made at any point without drilling or welding. These trays simplify engineering design, production, transport, and on-site installation, making them an ideal choice for cable management.
Long-Span Cable Trays:
Long-span cable trays are designed to bridge greater distances between supports than standard cable trays. Thanks to their sophisticated structural design, they offer superior load-bearing capacity. They are suitable for overhead indoor and outdoor cable laying in sectors such as oil refining, chemicals, textiles, machinery, metallurgy, power generation, and broadcasting. They are also ideal for underground infrastructure, serving as supports within cable trenches and tunnels for projects like subways and civil air defense facilities.
The long-span cable tray series includes ladder, tray, and trough types, as well as heavy-duty ladder trays, right-angle tees, multi-section tees, right-angle crosses, and corresponding connectors, covers, and support posts.
Covers are available for long-span cable trays; please specify the need for covers when ordering or order them by their specific model numbers.
Surface treatment options include plastic powder coating, galvanizing, or baked enamel finishes. Plastic-coated trays are recommended for corrosive environments, while galvanized trays are suitable for general atmospheric conditions. General Terms
Main Components of Cable Tray Systems:
The support structure for cable tray installation consists of uprights (vertical posts) and cantilever arms (brackets). The upright serves as the primary load-bearing component, while the load from the cable tray is transferred to the upright via the cantilever arm. Thus, uprights and cantilever arms are the two key components in the installation of cable tray systems.
Aluminum Alloy Cable Tray:
An abbreviation for a cable tray system made of aluminum alloy. It is an integrated assembly with a continuous rigid structure designed to support cables, comprising straight sections, fittings (such as bends), supports, and hangers made from aluminum alloy materials (configured as trays or ladders).
Ladder-type Cable Tray:
Refers to the specific component that directly supports the cables; it is a ladder-like structure composed of two longitudinal side rails and multiple rungs.
Perforated Tray:
Refers to the specific component of a perforated trough-type cable tray that directly supports the cables; it is a trough-shaped component with a perforated bottom, formed either by assembling a perforated base plate with side rails or by punching and bending a single sheet of aluminum alloy.
Solid-bottom Tray (Non-perforated Tray):
Refers to the specific component of a solid-bottom trough-type cable tray that directly supports the cables; it is a trough-shaped component with a solid bottom, formed either by assembling a solid base plate with side rails or by bending a single sheet of aluminum alloy.
The LQJ series aluminum alloy cable tray is a corrosion-resistant system. It features a simple structure, innovative design, and excellent corrosion resistance; it is easy to install and maintain, requires no routine upkeep, and is suitable for a wide range of environmental conditions.
Based on structural design, the LQJ series aluminum alloy anti-corrosion cable trays are categorized into types LQJ-A, B, C, and LQJ-LPC. The former types utilize extruded aluminum alloy profiles with various cross-sectional shapes to fabricate side rails and rungs, allowing for the creation of ladder, tray, or trough structures to meet diverse application needs. The latter type (LQJ-LPC) is manufactured by bending aluminum sheets to form trough-style cable ducts and various specialized fittings, catering to specific cable routing requirements. After being extruded and formed, LQJ-A, B, and C series aluminum alloy profiles undergo solution treatment and artificial aging; this process not only enhances corrosion resistance but also increases the alloy's strength, thereby ensuring a high load-bearing capacity for the cable trays.
The surfaces of the LQJ series anti-corrosion aluminum alloy cable trays are treated with anodizing, providing superior corrosion resistance and the advantages of long-lasting durability and maintenance-free operation; they are particularly suitable for use in environments characterized by high temperatures, high humidity, and heavy salt spray.
