THHB environmental protection gas insulated ring main unit

Overview: Nitrogen or dry compressed air is used as the insulating medium, and the principle of vacuum arc extinguishing is adopted. The amount of cyclopropane resin is 10% of the solid cabinet, and there is no SF6 greenhouse gas emission. It is an environmentally friendly switch cabinet in the true sense. The THHB environment-friendly gas-insulated ring network cabinet vacuum bubble developed by Tellhow Technology is in direct contact with the gas, ensuring that the temperature rise meets the requirements of the national standard. The conductive part adopts electric field shielding technology to ensure the uniformity of the electromagnetic field and effectively control the temperature rise. At the same time, in order to ensure the safety of the operation of the equipment, the electrical gap between the conductive parts is increased, and the operation under the condition of zero gauge pressure can also ensure the safety of the operation.
