Electrical network with electric lighting consists of external power cable; process cable, which is used when inflating (installing) the module; electrical switchboard with circuit breakers and a ground fault circuit interrupter (GFCI); on-board (internal) cable, special pendant lights with LED lamps. Electrical network is resistant to bending at temperatures down to -60°C. On-board (internal) cable is laid in the module at the manufacturing stage and is not dismantled later, which significantly reduces the time of module deployment. The use of LED lamps can reduce power consumption by up to 10 times while maintaining the required illumination.
