Aluminum Alloy Cable Trays from Japan

Japanese aluminum alloy cable trays, such as the LQJ series, are lightweight, corrosion-resistant, and available in ladder, trough, and tray types with flexible installation and high load capacity.

Material and Corrosion Resistance

Japanese aluminum alloy cable trays are made from high-quality aluminum alloys with excellent corrosion resistance, achieved through a natural oxide layer (alumina) that protects against atmospheric and industrial environments. These alloys are selected for mechanical strength, hardness, and resistance to stress corrosion, cracking, and pitting. The lightweight nature of aluminum also facilitates easier handling and installation compared to steel trays.

Structural Types

The LQ

J series offers three main types of cable trays: Ladder Type (T): Features two longitudinal side rails connected by transverse rungs, providing excellent ventilation for cables but limited dust and interference protection. Trough Type (C): Enclosed design that is dustproof and interference-proof, suitable for sensitive control or communication cables. Tray Type (P): Solid-bottom design for general cable support, offering a balance between ventilation and protection.

Dimensions and Load Capacity

Standard tray length: Up to 6 meters; longer lengths available on special order. Load capacity: Varies by type and cross-sectional design; ladder and trough types are engineered for high load-bearing while maintaining a compact structure. Side rails: Typically C-channel profiles for ladder trays, providing rigidity and vibration resistance.

Installation Features

Lightweight aluminum allows for easier installation and handling. Modular design supports flexible construction and future cable additions or modifications. Swaging or bolted connections ensure strong mechanical and electrical continuity.

Zero tangent fittings reduce space requirements when parallel trays are installed close together.

Standards and Certification

Japanese aluminum alloy cable trays are designed to meet international standards, often equivalent to American material standards, and comply with UL, CSA, and NEMA VE-1 classifications. This ensures safety, reliability, and compatibility with industrial and commercial electrical systems.

Applications

These trays are widely used in factories, ships, offshore platforms, and other industrial environments where standardized, safe, and efficient cable management is required. Their combination of high load capacity, corrosion resistance, and flexible installation makes them suitable for both power and communication cabling.
