The 10kVA Completely Self-Protected (CSP) Single Phase Pole Mounted Transformer is an oil-immersed distribution transformer designed for overhead power distribution networks. Equipped with built-in overload protection, internal circuit breaker, and surge protection, it automatically disconnects under fault conditions, minimizing maintenance and improving system reliability.It is widely used in residential areas, rural electrification, utility distribution networks, and light commercial applications where enhanced transformer protection is required.
Zisheng ELECTRIC the production of 10 kVA Completely Self-Protected (CSP) single-phase overhead transformers, meticulously engineered to meet international standards such as IEEE C57.12.00, IEEE C57.12.20, DOE-2016 Efficiency, CSA C2.1, and CSA C2.2. The 10kVA fully self-protected (CSP) single-phase pole-mounted transformer is an efficient and reliable power equipment designed for small and medium-sized power needs. The transformer adopts advanced fully self-protection technology and has built-in overload, short-circuit and overvoltage protection functions to ensure that the transformer can automatically cut off power under abnormal conditions, avoid equipment damage and improve system safety. It has a simple design, is easy to install, saves space, and is suitable for all types of power distribution systems. This transformer is suitable for residential, commercial areas and small industrial places, providing stable single-phase power output.
Zisheng are a professional 19+ years manufacturer in producing Oil-Immersed Transformers, Compact Substation, Pad Mounted Transformers, Pole Mounted Transformers and Dry Type Transformers. We own the certificates of ISO/CE/IEC 60076 and TUV Rheinland.

Product: 10kVA Completely Self-Protected (CSP) Single Phase Pole Mounted Transformer
Location: Mexico
Application: Residential Utility Distribution
A regional utility company in Mexico installed 120 units of 10kVA CSP Single Phase Pole Mounted Transformers as part of a residential distribution network upgrade. The project aimed to replace aging transformers, improve power reliability, and reduce maintenance requirements in suburban and rural communities.
Each transformer features an integrated secondary circuit breaker, surge arrester, and overload protection, providing automatic fault isolation and enhanced system safety without the need for additional external protective devices.
