Outdoor Telecom Cabinet

what’s outdoor telecom cabinet?

Outdoor telecom cabinet provides an outdoor environment and security for wireless comms or wired network sites. It is made of metal or non-metal materials. It is suitable for roadside, park, roof, mountainous, and flat ground areas. I

Outdoor telecom cabinet can hold base station, power, battery, temperature control, transmission equipment, and other support. It also provides mechanical and environmental protection to ensure normal operation of internal equipment.

Types of outdoor telecom cabinets

Heat exchange type

The heat exchanger acts as the temperature regulator for heat dissipation equipment. Heat is transferred through the heat exchanger cores that are divided by an air duct. The choice of heat exchanger should be selected according to the heating value of the equipment inside the outdoor cabinet.

Semiconductor (temperature-controlled)

Semiconductor devices are employed to lower the outdoor cabinet’s temperature. Without compressors, this refrigeration method enhances the system’s reliability for difficult external conditions. It’s commonly seen in Chinese telecoms, like China Unicom and Mobile.

Materials

Exterior of used outdoor telecom cabinets body is made of hot-dip galvanized sheet of ≥1.5mm thickness. After welding, it must be sprayed with outdoor powder. Heat-dissipating cabinet body uses ≥1.5mm hot-dip galvanized sheet plus 10mm thermal insulation cotton. Cooling type cabinet body uses same structure.

The cabinet is constructed of at least 2mm cold-rolled steel plate, welded and hot-dip galvanized.

Cabinets must possess corrosion and electrochemical resistance, with or without surface treatment, through their metal structure.

Non-metallic components (insulated wires, cables and foam) must be fire-resistant and meet flame-resistant standards.

Manufacturing process

Exterior
Surface must be flat, texture matching sample, no bumps, holes, breaks, chips, flaking, dust, drooping, undersides, or grime.

Unsprayed outdoor telecom cabinets should have a consistent and attractive exterior.

Adhesion
The cabinet’s surface coating passes the level 1 adhesion test according to GB/T 9286-1998.

Impact resistance
The cabinet’s surface coating passed the impact test with no radial cracks or gaps.

Anti-aging
The coating on the cabinet surface is anti-aging.

Solvent resistant
Once it passes the solvent test, the cabinet’s surface should still be glossy, retain its color.

Cabinet materials should be corrosion- and electrochemical-resistant, with or without a coating.
