Conventional standard wires, junction boxes, cables, corrugated products usually laid at various locations where the ambient temperature does not exceed 50 ° C (degrees Celsius).
These standard materials in areas where the environment has a temperature of more than +50 ° C, it is impossible to lay and install on the following compelling reasons for which the electrician just a month (maximum after one quarter) will be unfit for use in steam room:
- cable channels under the influence of heat ducts, and their covers deformed and fall off rapidly;
- corrugated assembly articles just skukozhivayutsya and even sintered;
- insulation of wires and cable products very quickly cracks and loses its insulating and protective properties;
- appear and increases the value of a person's life-threatening leakage currents, which may well bring severe electrical injuries, and even death of a person;
- there is the possibility of fire and hearth fires;
- occurrence of various outrages and even complete failure.
When installing the electrical parts in hot environments need to buy heat-resistant one and two or three wedges electric wire marks RKGM or PRKS (it has a circular cross section in the form of conventional cord, but with a more rigid insulation). Their cable insulation to withstand the ambient temperature to 100 degrees at 90-100% relative humidity.
These wires can be installed in cabins in two ways:
- on insulators;
- using metal staples, nails, screws, steel tape, etc.
For installation of heat-resistant wire braid double or triple braid of wires, as it does every girl, and lay it on the insulators. Electrical wiring in hot areas desirably is better not connect at all between them. But if you still need to connect them, then it is better to use the crimping sleeves or welding to produce them.
Other types of connections: screws, type "vago" terminals with caps and even ration will be in operation in the heat of insecure work. So long as the heating causes their linear and volumetric expansion of the metal as a result of mutual contact is broken and is the destruction of connection terminals made on the basis of plastic, that is, there is a complete physical degradation.
Important tips!
- In the steam room is impossible to mount the electrical outlet switches lamps, they can be installed just outside the steam room.
- As the use of mains voltage electrical wiring, it is best to apply the safe voltage of 12 volts, instead of 220 V.
- As emergency lighting You can use compact fluorescent lamps with finger batteries or rechargeable batteries that can be recharged periodically.
- Electrical network must mounted with RCD (residual current device), which disconnects the power supply at a current leakage of 10 to 30 mA.
- Lighting should be located out of range: outside the shelf for soaring at a height of 2.25 meters from the floor lamps and they should be in the deep plastic bowl is light, and have the necessary degree of protection on humidity.
