In the industrial setting transformer reliablity goes hand and hand with the environmental responsibility. Oil leaks can cause serious environmental harm, fines, and operational shutdowns the Yawei transformer are integrates robust oil containment system into its tank substation and providing essentials protection for both operational and the environment. Bunded double well tanks offer top level environmental protection by enclosing a primary tank within secondary outer tank. Any leakage from the inner tank is contained and the space between the walls is continuesly monitored for breaches. This design provides highly reliable secondary containment and essential for sensitive ecosystem or the areas near in the water. For smaller transformer and auxilliary equuipment Yawei provides spill containment pallets that can hold 110% of the transformer oil and meeting the environmental standards. Oil absorbent matts and socks arouond connection and valves offer additional protection against minor leaks and preventing spread and allowing quick cleanup. YAwei containmenetsystem helps the customers comply with EPA and SPCC regulationby providing documentation, material certification and guidance in the ins-ectiion mostly the maintennance, Using this equuipment ensure the adherance to current environmental protection standards. Yaawei integrates active protection system alongsie passive containment, the eemergency shut off valves triggered automatically or manually isolate the transformer to prevent oil spills levels. This combined with remote monitoring of oil levels, pressure and tank integrity, these system provide immediate alerts to staff for promt intervention.
