Gas Insulated Switchgear (GIS)
We can install GIS from 33kV up to 275kV including SF6 gas handling by our compentent personal.

EHV Transmission Substation
Our team are specialize in high voltage substation installation including circuit breaker, current transformer, voltage transformer, gantry, string, cabling, earthing and all related work.

Profesional Team
We have professional team in both design and installation work including site supervision, project management, electrical competent person, skilled worker along with plant & machinery.

Transformer & Reactor
Supply
We are appointed as the local agent by TBEA ShenYang Transformer Co. Ltd. We can provide support to supply their transformer which is one of the world leading transformer brand. They are also listed as approved brand in Sarawak Energy approved vendor list.
Installation
Our team are equiped with all the necessary machineries and skill worker to perform installation work including assebly, vacuuming, oil filtration and oil testing. We had installed various size of transformer all the way up to 275kV.
Maintenance & Servicing
As we have adequate tools, machineries, and worker with experience, hence we also assist factories to perform preventative maintenance and servicing work to their transformer & reactor to ensure they are oprating in good condition and minimize its down time.
Gas Insulated Switchgear
Installation
We had sent our team to supplier factory to accept training for GIS installation and have been working under multiple supplier's specilist to install GIS at multiple site.
SF6 Gas Handling
SF6 gas is one of the most stable gas which is why it had been widely used as insulator inside switchgear. However it is also a harmful green house gas, 1 kg of SF6 gas has the same impact of 23,500kg of Co2. Hence it can cause globle warming 23,500 time higher than Co2. Also it is a stable gas, hence it will stay in atmosphere for long period of time. In order to protect our earth, we handle the used SF6 gas properly to prevent it been release into our atmosphere. Our team are also trained by SF6 gas specilist on how to handle the gas properly.

Tondong 275/132/33kV Substation
Tondong 275/132/33kV Substation is the largest substation in Kuching constructed by SMSB-PPKSB Consortium. We play a roll as erector to install all electrical equipment. There are 26 bays of 275kV switchyard, 11 bays of 132kV switchyard, 2 units of 240MVA transformer, 8 nos of reactor, complete cable trench, cable ladder, power cable, multicore cable, earthing and lighting system.
Few years after we completed the project, it was commissioned in 2022. In year 2023, Hitachi Energy Sdn Bhd was awarded for Tondong Statcom extension. We are also was involved in the installation of statcom project. Currently the project is completed and commissioned successfully.

Kemantan 132kV CT & 36kV NCT Replacement
YPN Electrical Engineering & Construction (Sarawak) Sdn Bhd was awarded this project in year 2022 to replacement CT and NCT at Kemantan Substation.
We supplied 19 nos of TBEA CT and 2 nos of RITs NCT including all necessary accessaries to completed the job. The replacement work was carried out on 15 Jan 2024 - 28 Jan 2024. All CTs was commissioned successfully as planned.
