Product Description
What is the Pad box type substation /Pre-fabricated box substation?
Pad mounted substation refers to a new type of substation that can be put into use through simple assembly after the completion of factory production, the whole substation products in the form of a whole, through the means of transport to the user's site at once.
Second, what are the characteristics of Pre-fabricated box substation?
1. Convenient installation: Pre-fabricated box substation adopts overall modular design, reducing the amount of on-site construction, fast installation, greatly shortening the construction cycle of the substation.
2. small footprint: Pre-fabricated box substations are smaller in size and cover a smaller area than traditional substations, saving land resources.
3. environmental protection and energy saving: Pad mounted substations products with the overall sealing structure, the materials used in line with environmental requirements, without the need for additional construction of the machine room, will not pollute the environment, has a very good environmental protection and energy saving effect.
4. corrosion resistance: Pad mounted substations using high-quality anti-corrosion materials, can improve the service life of the equipment, and effectively slow down the aging of the equipment, reducing the operation and maintenance costs.
5. Convenient operation and maintenance: Pad mounted substation has intelligent operation function, which can achieve remote monitoring, and in case of failure, it can be quickly located for easy maintenance
