Brief Description
APAR provides end-to-end installation services for Optical Ground Wire (OPGW), All-Dielectric Self-Supporting (ADSS) cables, and associated hardware for power transmission, distribution, and telecommunication networks.
Leveraging extensive expertise in power infrastructure and fiber optic network deployment, APAR delivers turnkey solutions covering engineering, supply, installation, testing, commissioning, and maintenance support. Our solutions enable utilities, telecom operators, railways, and infrastructure developers to establish reliable communication backbones while maximizing the utilization of existing transmission and distribution assets.
We specialise in the live line (hot line) replacement of existing earthwire/OPGW with new OPGW on 66kV to 765kV transmission systems. We have installed 23,963 Kms of OPGW with approximately 23000 Kms in Hot Line (live line) conditions.
We offer live line/off line installation on 33kV to 765kV transmission systems by replacing the existing earthwire, aviation globules and associated hardware.
