Refurbishments And Upgrade
C-AFRICA’s designers and construction experts recognise the benefits of adhering to the site grounding and electrical industry standards developed by major manufacturers like Harris and Motorola. We also recognise that sites constructed in strict accordance with grounding standards stand a better chance of surviving weather-related problems than those that have not been constructed according to standards. A thorough adherence to site development standards will guarantee security. We focus on on-site security and site hardening processes. Our tower operators take proactive steps to protect Telecom towers, transmitters and transmission wires from both human and environmental threats.
Site Security
We built a tower to such rigorous standards, which gives the necessary strength to survive the worst that natural disasters during their life cycles. We secure transmitter sites and buildings by following these steps;
- Enclosing the site with razor wire-topped wire mesh
- Eliminating glass windows and non-metal entrances
- Installing alarms to the doors
- Installing security cameras
- Keeping grass and bush trimmed to minimise wildfire damage
Site Hardening Process At Transmitter Houses And Transmitter Buildings
We pay attention to details at the sites focusing on cable layout, strict quality control in the installation of equipment and interconnecting cabling. We encase tower anchors and bases with heavy steel to prevent the possibility of vital cables being either damaged or cut.
- We secure transmitter houses installed in two-way radio sites with reinforced, precast concrete
- We use heavy-duty cranes to lower the transmitter buildings onto concrete pads
- Our teams will add thick steel doors and enclose the cables in rigid PVC
- Two-way radio operators are reinforced using the sub tetra controlled environment vault power-wave technologies
- Our teams will then reinforce this with watertight fiberglass buried below the concrete, leaving a smooth surface slab disguised with a park looking bench
- A gasket rain shelter is used to shelter the sub tetra from flood water
- For servicing purposes, our technicians will activate the inbuilt hydraulic elevator which lifts the transmitter above the round for easy access
- We shall encase valuable copper in PVC pipes to protect from thieves
- We then tack weld the gates, to make them immovable and stronger
Site Hardening Against Threats
Shelters are also designed to meet wind load specifications. We use Dual HVAC systems to ensure that equipment can be maintained in the event of a single HVAC failure. The transmitter site’s electrical system is equipped with a power-line conditioner to prevent carrier-current transmissions. The power line conditioner is sealed and inspected regularly.
