Product Description

As the professional manufacturer, we would like to provide you high quality Square Frame Composite Insulation Crossarms. To this end, Shandong Taikai Electrical Insulation Co., Ltd. has developed a square composite insulation cross-arm. This product can withstand most induced lightning strikes and avoid tripping and subsequent accidents caused by flashover. In 2017, a 10kV rod-frame composite insulation crossarms was piloted. Due to the large size and weight of the product and the inconvenience of operation during installation, the 10kV rod-frame composite insulation crossarms was cancelled.In 2018, it was recommended to use square tube-frame composite insulating crossarms to facilitate the installation and use of the product.


In mid-2019, the State Grid Equipment Department organized a review meeting on the technical specifications for bidding for composite insulated cross arms for 10kV distribution lines. It was proposed that the hollow square tube insulated cross arms could not meet the technical requirements in test items such as dye penetration, water diffusion, and sealing tests. The use of square tube-frame composite insulating crossarms is stopped, and a new type of 10kV composite insulation crossarms is planned to be developed. It is recommended to use Square Frame Composite Insulation Crossarms and T-frame composite insulating crossarms.


Shandong Taikai Electrical Insulation Co., Ltd. now has 4 of the most advanced fully automatic high-temperature injection vulcanizing machines in the industry of 550t, 660t, 1100t, and 1800t, and 2 automatic crimping machines with acoustic detection, which can be used for 10kV Square Frame Composite Insulation Crossarms Production.
