Current product lines:

  1. ALUMINUM COMPOSITE CORE CONDUCTOR (ACCC)

Inventor: CTC GLOBAL (USA)

 

CTC Global/USA Group has successfully developed aluminum composite core conductor (ACCC) to replace traditional ACSR conductor. This is a particularly effective solution both technically and economically in the reconductoring and the replacement conductor projects of the transmision line as it allows the use of the existing tower system to increase the capacity by more than 2 times, without increasing of the weight of the conductor or load applied to the tower system. The sag of the line is also improved compared to the existing line due to the low thermal expansion coefficient of the composite core (1/12 times that of the steel core). Using ACCC conductors with the same weight as existing ACSR conductors reduces losses by 30% when operating at the same current (the amount of aluminum increases by 28% compared to existing ACSR conductors). The installation of ACCC conductor is fast, does not require special skills, reduces power outage time and does not require special installation tools and equipment compared to the existing capacity of construction companies in Vietnam …

Up to now, ACCC conductor has been present in over 60 countries with over 1,100 projects and more than 250 trusted customers. In Vietnam, there have been over 70 projects with more than 7,000 km of ACCC conductor installed.

The product range of ACCC conductor is very diverse, there are up to 35 types of conductor with sizes ranging from 150 mm2 to 1400 mm2. Corresponding to each type of conductor, the manufacturer has coded matching accessories so that customers have many more easy options to choose from.

Since 2020, manufacturer CTC Global has upgraded its ACCC conductor with a composite core version with 4 optical fibers inside (InfoCore). With this new type of ACCC conductor, we can check the quality of the conductor after installation to ensure the safety of the conductor before energizing.

VTD is the representative of CTC Global in Vietnam. We are committed to providing customers with products and services, design consulting, installation supervision by trained experts and Master Installer certificates issued by CTC Global, operation & warranty from the manufacturer.
