Scope of application:
Connections and internal power lines for power, lighting, electrical installations, instrumentation and telecommunications equipment with rated AC voltages up to and including 450/750V.
General requirements: economic and durable, simple structure.
Special requirements:
1) Outdoor laying, affected by sunlight, rain and freezing conditions, requires atmospheric resistance, especially solar aging resistance; There are cold resistance requirements in severe cold areas;
2) In use, easy to be damaged by external force or flammable, and oil contact very many occasions should wear the pipe; When the pipe is worn, the power line is subjected to greater tension, and there is the possibility of scratching, lubrication measures should be taken;
3) As the internal use of electrical equipment, when the installation position is small, there should be a certain degree of softness, and the insulation core color separation should be clear, should be matched with the corresponding connector terminal and plug, so that the connection is convenient and reliable; For the occasion of anti-electromagnetic requirements, the shielding power line should be used;
4) For the occasion of high ambient temperature, sheathed rubber power cord should be used; For special high temperature application of heat-resistant rubber power cord.
