YJHBZ (S) -32/85 (34/90) type 630A shielded and connected to lightning arrester

YJHBZ(S) -32/85（34/90）  
Product Introduction:
The rear joint lightning arrester is mainly used for electrical equipment such as ring main units and distribution boxes.  
Product features:
The rear joint lightning arrester provides lightning protection and overvoltage protection for electrical equipment. The pressure release device ensures that the lightning arrester remains intact even under fault currents of 16kA and 800kA. Good nonlinear resistors enable lightning arresters to have residual low voltage, same current capacity, fast response time, and flat steep wave characteristics, ensuring the operation of power transmission and transformation equipment.  
Adopting a unique explosion-proof device, the lightning arrester can reliably operate in the event of long-term operation degradation or damage due to lightning strikes under any grounding method at the neutral point. Effectively prevent lightning arresters from exploding and permanent grounding faults in the power system, ensuring the safe operation of the power grid.  
The rear joint lightning arrester is a fully insulated, fully sealed, and fully shielded product.
