Introduction of the cause and consequence of power cable fever
Power cable by a certain load current, will be hot, with the increase of load current and cable surface temperature is higher, if not handled in time, the consequences. Such as: polyvinyl chloride (PVC) cable, wire core temperature of 70 degrees is limit considered, low surface temperature will be 5 ~ 10 degrees. So the cable surface temperature under 60 degrees basic is safe, considering from the power maintenance, the lower the temperature, the better, of course.
In the operation of the cable in heating reasons are as follows:
1. Cable conductor resistance does not conform to the requirements, resulting in cable heating phenomenon in running.
2. Cable wide choices, the use of the conductor cross section of the cable is too small, in the operation of the overload phenomenon, after long time use, the heating and cooling of the cable have fever due to unbalanced phenomenon.
3. Arrange too dense, cable installation, ventilation cooling effect is not good, or cable near too close to other sources of heat, affected the normal heat dissipation of the cable, may also cause cable heating phenomenon in running.
4. Joint manufacturing technology is bad, no pressure to close, cause whenelectrified resistance is too large, also will cause the cable to produce hot phenomenon.
5. Cable insulation is not good, cause the insulation resistance is small, also can produce in the operation of the heating phenomenon.
6. Armored cable, local sheath damage cause slow damage to insulation performance, after the water gradually reduce insulation resistance, can cause heating phenomenon in the operation of the cable.
After cable heating phenomenon, if you don't find out why timely troubleshooting, continuous electric cable to continue after the operation will produce heat insulation breakdown phenomenon. Cable causing interphase short circuit trip phenomenon, serious may cause fire.

Several questions need attention when install fire-resistant cable
Fire resistance cable can still maintain the normal work of the line for a period of time under the condition of combustion, that is to say in case there is on fire, fire-resistant cable won't suddenly burning, it still can maintain the normal power supply for a period of time. This feature determines the fire-resistant cable in modern urban and industrial construction plays an important role, because once the fire, control, monitor, guide and alarm systems such as power supply circuit must maintain normal work.
Fire-resistant cable applications:
Fire-resistant cable is mainly used in emergency power supply to the user of fire equipment, fire alarm equipment, ventilation and smoke exhaust, guide line lights, emergency power socket, the elevator for the emergency power supply circuit.
Staff need to pay attention to the following questions when install fire-resistant cable:
1. When fire-resistant cable used for cable populated in the cable tunnels, cable interlayer, or inflammable places near tubing, oil depot, fire-resistant cable shall, first of all, choose A category. Despite the situation, and the less number of cable configuration, should choose B type fireproof cables.
2. Fire-resistant cable mostly used as emergency power supply circuit, the normal work of the requirements of fire. Due to the fire when the environment temperature has risen sharply, to ensure the transmission capacity of lines, lower pressure drop, long for the power supply circuit and the circuit of the voltage drop strictly limit allowed, fire-resistant cable should be at least one.
3. Fire-resistant flexible cable cannot be used as a high temperature resistant cable.
4. In order to reduce cable joint failure probability in fire accident, should try to reduce the amount of joint in the installation, to guarantee the normal work of the lines in the fire. If you need to do to branch connection, deal with joint completes the fire prevention.

Manufacturing process of Nylon sheathed wire
Due to the nature of nylon material have different from ordinary plastic, therefore we put forward some unique technical requirements in the extrusion process.
Drying process. Because the nylon material is medium polarity, easy absorption of moisture, according to Nylon sheathed wire material manufacturer, when the nylon material moisture content exceeds 0.3%, cannot squeeze, found in the actual production process, the nylon is expected to be affected with damp be affected with damp, extrusion sheath will blister, such as foam, granular material or damaged. Nylon material itself with vacuum bag vacuum packaging, not broken packages can be directly put into use, but such as transportation damage, sealed or open package are not finished in time, etc., must be dried before use.
So be affected with damp be affected with damp dry nylon material should be done before using. Had better use of pumping air into vacuum state, rotating barrel heating to remove moisture, each drying amount shall not exceed 3/5 dryer volume. Such as the capacity is too big, inside the dryer materials difficult to rotate, cause uneven heating, short time water is difficult to remove all, time is long can make the yellow part material oxidation, unable to meet the requirements of sending out surface. Vacuum degree of vacuum should reach more than 0.05 MPa, or it will be hard to remove moisture, if by steam heating, to control the heating temperature, amount of water vapor temperature appropriate for 80 + / - 50 ℃, the heating temperature is too high the nylon wire material oxidation and become yellow.
