Communication Cabinet Manufacturer | Outdoor Communication Cabinet Solutions

I. Overview of Outdoor Communication Cabinet

As a professional communication cabinet manufacturer, we provide high-performance outdoor communication cabinets designed for telecommunications, data transmission, and outdoor network infrastructure applications.

The outdoor communication cabinet features a modular structural design consisting of one main equipment compartment and three auxiliary compartments, with customizable external dimensions according to customer requirements.

The cabinet body is manufactured using 45mm thick color steel sandwich panels, combined with a 200mm high galvanized steel base with a thickness of 2.0mm, providing excellent structural strength, insulation performance, and environmental protection.

The cabinet is designed to support the installation of OLT main equipment, while also providing dedicated installation space for environmental monitoring systems, power distribution units, embedded DC power supply systems, PLC equipment, and other communication devices.

The internal layout is divided into two main areas:

Upper compartment: Designed for communication equipment installation, including OLT and network devices.
Lower compartment: Dedicated battery compartment, supporting battery configurations up to 150Ah/48V.

This optimized design improves equipment integration, maintenance efficiency, and overall system reliability.

Door and Lock System Design

The cabinet door adopts an embedded handle structure with a compact sealing design, improving waterproof and dustproof performance. The door opening angle exceeds 110°, providing sufficient operating space for equipment installation and maintenance.

The cabinet door is equipped with a reliable limiting mechanism, which effectively restricts movement when the door is fully opened, ensuring safe operation even under outdoor conditions.

The locking system adopts a three-point locking structure consisting of pull rods and locking plates, offering strong mechanical strength, excellent security performance, and enhanced anti-theft protection.

Door and Door Limiter Features

The cabinet door system is designed with the following features:

Vertical hinge structure for stable operation;
Door limiter automatically engages when the door is opened;
Manual release function when closing the door;
Maximum opening angle greater than 110°;
After more than 1,000 opening and closing cycles, the door structure and limiter maintain reliable performance without excessive wear;
The door limiter can withstand static loads generated by wind speeds of 19m/s without mechanical damage or functional failure.

Ventilation Window and Filter System

To ensure proper airflow while preventing dust, insects, and small animals from entering the cabinet, the ventilation system adopts a multi-layer protection design.

Air Outlet Protection

A 1mm thick, 16-mesh stainless steel insect-proof mesh is welded to the ventilation outlet, effectively preventing external contaminants from entering while maintaining ventilation efficiency.

Air Inlet Filtration

The air inlet is equipped with a corrosion-resistant dust filter assembly consisting of:

10mm thick filter material;
30ppi filtration density;
Pleated support mesh structure;
Aluminum frame fixing design.

The modular filter assembly allows quick replacement and convenient maintenance.

Rainproof Ventilation Design

The fan outlet is installed at the upper edge of the top cover. The louver structure guides rainwater downward, while an additional waterproof structure prevents rainwater from entering through the ventilation opening, ensuring reliable operation in outdoor environments.

II. Main Features of Outdoor Communication Equipment Cabinet

1. Excellent Outdoor Protection Performance

The cabinet is designed for harsh outdoor environments and provides comprehensive protection against:

Dust;
Direct sunlight;
