Introduction of the Ten Advantages of Copper Core Cable



1 Conductor adopts oxygen-free copper in line with the standards of the International Electrotechnical Commission. 

High-precision oxygen-free copper also meets the requirements of national standards. 

It has good flexibility, low electrical resistance, low power transmission loss, long service life and tin plating on the surface. 

Corrosive and anti-oxidation properties are more excellent.


2  It adopts high-quality halogen-free low-smoke fire-retardant and fire-resistant magnesium oxide as insulation. 

The material meets the requirement of halogen-free low-smoke environmental performance and meets the requirements of low-insulation resistance, good voltage resistance and good puncture resistance.


3 Using oxygen-free copper that meets the standards of the International Electrotechnical Commission as the outer sheath.

It is the special material that determines the high mechanical strength, and secondly, when the cable is crushed by the external force to 2/3 of the original cable diameter, the current-carrying surface can still be maintained. 


4 Since the materials constituting the cable are all inorganic materials (copper and magnesia), without any flammable medium, the cable can be normally energized at a temperature close to the melting point of copper, and the fire resistance is excellent.

So it is a fire protection system and requires safety. The place replaces the trending product of flame retardant and refractory cables.


5 The copper sheath is made of seamless copper tube, so the water can enter the cable without any way, and it has excellent waterproof performance. 

It is an ideal choice for underground places with large humidity such as subway and tunnel.


6 The cable allows long-term working temperature up to 250 ° C. 

It can be close to the melting point temperature of copper in a short time or very period. 

It is much higher than the plastic "high temperature cable". 

It is the most hot working area in steel mills, copper factories and aluminum plants.


7 The resistance of the insulation material does not change after the product is irradiated. 

It is an ideal distribution cable in nuclear facilities. 

At the same time, the cable copper sheath forms a natural and optimal shielding layer, which is an economical and safe product in key places such as computer room, power dispatching and control room.


8 Compared with ordinary cables, these products have a 60% reduction in volume and a 30% weight reduction. 

Due to its high corrosion resistance and high mechanical strength, this product has a long life and its life span is over 100 years.


9 Compared with plastic cables of the same cross section, the current carrying capacity of the magnesia cable can be increased by more than one section. 

At the same time, it can withstand considerable overload, and its overload capacity can reach more than 100 times of the normal current carrying capacity.


10 The copper sheath provides good low grounding resistance, acts as a grounding and eliminates the need for a separate grounding core.
