CFRP Carbon fiber composite core

Product introduction:

The Carbon fiber composite core (Carbon fiber reinforced and resin compounded based composite rod) has been engineered base on epoxy polymer resin, its interior is strengthened by carbon fiber and exterior is reinforced by glass fiber, it has been produced by using pultrusion technology. The final product is a new breed of high performance composite material harbored tremendous prospect in the area of electrical transmission and others.

The Carbon Fiber Composite Reinforced Aluminum Conductor (ACCC or ACCR) is a new type of non-homogeneous electrical transmission conductor; it incorporates a high strength carbon fiber rod as strength member wrapped with aluminum strands to replace steel based of conventional conductors.

Specifications

1.  Carbon fiber composite reinforce core

High strength, its tensile strength is 2 times as that of steel

Light weight, its density only one quarter of the steel

High temperature tolerance, the linear expansion coefficient is very small

Corrosion resistance,  fatigue resistance,  extended life span

 

2.  Carbon composite core conductor

(1)High strength. It is 2 times as that of normal conductor.

(2)Improved capacity, increased ampacity and energy efficient. The composite reinforced conductor reduces transmission lost under the same load by 6%. It has 2 times of the ampacity compare with the conventional conductor under the 180℃ test condition thanks to its superior aluminum cross sectional area which is 1.29 times of that of conventional counterpart with equal outer diameter.

(3)Low sagging. It improves the safety and reliability for the conductor by reduces sagging up to 50% than the normal conductor at elevated temperature level.

(4)Light weight. The composite reinforced conductor reduces weight by between 10%-20%, because its proportion is only one quarter of the conventional steel conductor.

(5)Corrosion resistance. It doubled life span compares to the conventional conductor, because it has eliminated corrosion issued occurred from corrosive chemical reaction rose between aluminum strands and zinc coated steel parts.

(6)Energy efficiency and less environment impacts. The aluminum depletion reduced by 50% compares to the normal steel conductor under the same double capacity conditions.

(7)Reduces network costs. Because the carbon fiber reinforced composite conductor can increase conductivity, high ampacity, double capacity, increases the distance between transmission towers and reduced height of the towers, so it will reduce network installation costs compare to conventional conductors under the same condition.
