HAZARDOUS
Hazardous conditions can exist in places where volatile fuels are handled and pumped routinely. MI cable fittings are designed to meet the explosion and flame path requirements, and pre-terminated MI cable is used in these locations, particularly where they can replace bulky and rigid wire in conduit and conduit seal-offs.
Airports present unique safety challenges as aviation fuel is pumped from storage facilities to planes in close proximity to high volumes of passengers and personnel. Safety systems take priority in the design of airports, as real life airport fires have all-too-vividly demonstrated the severity of panic and confusion that can be created by smoke and loss of power. Accordingly, the circuits feeding fire pumps, emergency equipment and fire alarm system notification circuits are all-important and must maintain integrity throughout a fire. Tyco Thermal Controls offers a complete range of mineral insulated and polymer fire-rated cables to meet these requirements.
HIGH TEMPERATURE
Conventional wiring cables are generally limited to 90°C (195°F) operating temperatures. Environments where temperatures up to 670°C (1238°F) are encountered require special cabling.
CORROSIVE
Copper is good for many environments; but not all. For those environments where chemicals exist that are harmful to MI, a jacket is extruded over the cable sheath to protect the copper.
EMERGENCY POWER SUPPLY
Emergency generators are brought into play when regular power fails, and are the backbone of the systems that provide time for a safe evacuation of occupants, and power to operate the life safety and fire fighting systems.
FIRE PUMPS
Perhaps the most important fire fighting piece of equipment, the fire pump ensures water pressure for the sprinkler system. Mechanically tough, fire-rated wiring is needed for this critical circuit.
PRESSURIZING FANS AND SMOKE DAMPERS
For stairwells and other areas of safe refuge, pressurization fans and smoke dampers provide a positive pressure to maintain a smoke free area of safe refuge with clean air for breathing, and visibility for egress.
SMOKE VENTING FANS
Smoke is the major threat because of loss of visibility and air to breathe, and fans to remove smoke are of crucial importance.
EMERGENCY LIGHTING
When normal power is disrupted in a fire, the chances of safe egress or firefighting in the dark go down dramatically. Emergency lighting provides the back-up for the normal lighting.
FIRE ALARM
The National Fire Alarm Code stipulates that in Voice Evacuation Fire Alarm systems, the wiring for the notification circuits shall be 2-hour fire rated. Fire Alarm wiring designed to meet the survivability requirement for notification circuits is required.
POWER FEEDERS
The space savings achievable using MI or Raychem MC versus conduit and wire are huge - up to 80% space saving. In addition, the ease with which they can be pulled into difficult runs with tight corners gives them an overwhelming advantage.
LOW EMI
Electromagnetic fields from high electrical currents in equipment, bus-duct or feeders can cause interference in PC screens and sensitive electronic equipment located adjacent to the source of the EMI.
