Applications of PVC FOAM BOARD in the Telecommunications Industry

I. Structural and Protective Components for Telecommunication Base Stations

• Base station enclosures and protective casings:
  Components such as signal transceivers, antenna shields, and outer covers of outdoor base station cabinets require resistance to wind, rain, corrosion, and heat insulation. PVC foam board has a density of only 0.4-0.8g/cm³ (much lower than metal materials), reducing the load on base stations. It is also UV-resistant and stable in temperatures ranging from -30℃ to 60℃, protecting internal equipment from rain, dust, and high temperatures without interfering with signal penetration (its non-metallic nature avoids signal shielding).
• Internal support structures for base stations:
  Equipment brackets and cable fixing frames in base station rooms need to be lightweight and insulating (to avoid interfering with circuits). PVC foam board can be cut and welded into custom-sized brackets, meeting structural strength requirements while its insulation prevents potential differences with metal equipment, ensuring circuit safety.

II. Protection and Organization of Telecommunication Lines

• Cable/optical fiber protection tubes and slots:
  Outdoor or underground optical fiber and cable conduits (such as anti-wear sheaths for overhead cables, isolation slots in underground pipelines) require insulation, corrosion resistance, and impact resistance. PVC foam board has excellent insulation (volume resistivity >10¹⁴Ω·cm), is non-conductive and non-thermally conductive, preventing line damage from friction, moisture, or acid-alkaline soil corrosion. Its toughness also allows it to withstand minor external impacts (such as rolling during construction).
• Indoor cable trays and management racks:
  In telecommunication equipment rooms and data centers, cables (fiber optics, network cables) are organized using trays. PVC foam board can be processed into custom-sized trays or racks with a smooth surface and easy cutting, adapting to the needs of different cable quantities. Its insulation avoids signal interference between cables.

III. Enclosures and Protective Parts for Telecommunication Equipment

• Enclosures for fiber optic distribution/splicing boxes:
  These devices, installed outdoors or in corridors, require moisture resistance, UV resistance, and insulation. PVC foam board, after surface treatment (such as coating or painting), effectively blocks water vapor and UV rays, avoids electrical leakage risks due to its insulation, and is lightweight and easy to install (30%-50% lighter than metal enclosures).
• Outer covers for signal repeaters/amplifiers:
  Internal equipment contains electrical components, requiring insulation and auxiliary heat dissipation (PVC foam board’s low thermal conductivity reduces the impact of external high temperatures on internal components). Its mechanical strength protects internal components from minor collisions, and its processability allows custom holes or grooves according to equipment specifications.

Conclusion: Core Advantages of PVC Foam Board in Telecommunications

• Lightweight: Reduces transportation and installation costs, especially suitable for high-altitude base stations or wall-mounted scenarios.
• Insulation and corrosion resistance: Avoids circuit interference or environmental erosion, ensuring the safety of communication equipment and lines.
• Ease of processing: Can be sawn, milled, glued, and printed, quickly adapting to the needs of different telecommunication components.
• Cost-effectiveness: Superior to most traditional materials in terms of comprehensive material costs, service life, and maintenance expenses.
