Fire and heat protection wrap for conduits, cable trays, other electrical transmission lines and gas and oil pipelines

A fire and heat protection wrapping system for wrapping conduits, cable trays, transmission lines, cables and other electrical transmission devices associated with the transmission of electricity and electrical signals;

• and gas and oil pipelines, comprising:
• a) a concentric composite laminate structure having a plurality of concentric layers for the protection of transmission devices which are exposed to high temperatures in excess of three (3) hours in duration;
• b) said plurality of concentric layers incudes an outer first layer, an inner second layer, an inner third layer and an inner core fourth layer for wrapping of transmission devices;
• c) said outer first layer being a fiberglass textile having an intumescent coating for resistance to fire, heat, water, and impact;
• and said outer first layer surrounding said inner second layer and having an inner surface wall in contact with said inner second layer;
• d) said inner second layer being a metal foil layer for reflecting heat and eliminating the convection transfer of heat;
• and said inner second layer surrounding said inner third layer and having an inner surface wall in contact with said inner third layer;
• e) said inner third layer being a low conductivity refractory blanket for reducing the transmission of heat;
• and said inner third layer surrounding said inner core fourth layer and having an inner surface wall in contact with said inner core fourth layer;
• and
• f) said inner core fourth layer being a water jacket layer for receiving water to absorb heat from a transmission device and functions as an endothermic layer;
• and said inner core fourth layer surrounding the core of a transmission device and having an inner surface wall in contact with a transmission device.
