Composite Insulated Cross-Arm
CICA is assembled from insulators and replaces the original iron crossarms and suspension insulator strings with a horizontal layout. The end sections are directly connected to the conductors using suspension fittings, achieving a compact tower design structure. This effectively reduces accidents and losses caused by flashovers while providing mechanical support and electrical insulation for overhead conductor systems.

The 500kV Datang Leizhou Power Plant Phase I Interconnection System Project in Zhanjiang, Guangdong, China in 2018.
The project is located in Leizhou City, Zhanjiang, Guangdong Province, China. This area is a typical coastal region with high salinity, located near the Qiongzhou Strait. The wind intensity is significantly higher than inland areas, and the region is also prone to severe weather conditions such as typhoons and heavy rainfall.

The TATA Power 220kV Composite Crossarm Project, India in 2022.
Using the CICA solution to optimize tower height while maintaining the existing corridor width, achieving the required airspace for aviation.
-
The Transelec 500kV CICA Project, Chile in 2022.
The conductor suspension point was raised by approximately 2 meters, effectively resolving the issue of insufficient ground clearance distance in the original line.
-
The 240kV Project, Canada in 2020.
The Canadian company aims to increase the ground clearance for the 240kV double-circuit lattice tower conductors in order to address land occupancy issues. They plan to replace the angle steel crossarms with dual-pole dual-tension composite crossarms to elevate the conductors and improve the ground clearance distance.
-
The 132kV Transmission Line Project in Hyderabad, India in 2019.
The project addressed the issues of restricted corridor space and inadequate ground clearance, thereby enhancing the safety and reliability of the power grid operation.
-
The 110kV Tianqing Line and 220kV Manxia Line Technical Transformation Project in Dali, Yunnan, China in 2018.
The project involved studying the use of composite material crossarms to reduce the corridor width of the line in Dali, Yunnan, China, taking into consideration the area's unique geographical environment with high altitude, strong UV radiation, and mountainous terrain. This approach improved construction efficiency while effectively reducing the risk of flashovers caused by lightning strikes, wind-induced deflection, bird damage, and other factors. Furthermore, it lowered operating and maintenance costs.
-
The 500kV Technical Transformation Project of the Dongsan Line in Jiangsu, China in 2016.
Since its commissioning in 2000, the line has experienced multiple instances of wind-induced deflection. Various methods to prevent wind-induced deflection have been employed, but they have not completely improved the effectiveness in preventing deflection-related tripping accidents.
-
The 220kV Maoqiang Line Transformation Project in Lianyungang, Jiangsu, China in 2022.
Located in a coastal area, the line has been severely corroded and has withstood multiple strong typhoons, yet continues to operate normally.
