General purpose rubber plastic power cord

1, the scope of application: ac rated voltage 450/750V and below the power, lighting, electrical equipment, instrumentation and telecommunications equipment connection and internal installation line.  

2, laying occasion and method: indoor open application and communication channel, tunnel along the wall or overhead laying;  Outdoor overhead laying, iron pipe or plastic pipe laying, electrical equipment, instrumentation and radio installation laying are fixed laying;  Plastic sheath power line can be directly buried in the soil for laying.  

3, general requirements: economic and durable, simple structure.  

4. Special requirements:  

1) Outdoor laying, affected by sunlight, rain and freezing conditions, requires atmospheric resistance, especially solar aging resistance;  Cold resistance requirements in cold regions;  

2) In use, easy to be damaged by external forces or flammable, contact with oil on many occasions should wear pipe;  When the pipe is pierced, the power cord is subjected to a large tension and may be scratched, so lubrication measures should be taken.  

3) For the internal use of electrical equipment, when the installation position is small, there should be a certain flexibility, and the insulation core should be clear color separation, should be matched with the corresponding connector terminal and plug, to make the connection convenient and reliable;  For occasions requiring electromagnetic protection, shielded power lines should be used;  

4) For the occasion of high ambient temperature, the sheath rubber power cord should be used;  Heat resistant rubber power cord for special high temperature applications.
