Sealing material.Chamber door is connected to cabinet with annealed copper wire, and ground connection symbol is indicated after mopping.Lockset is set on chamber door, is usually located
In blocking, prevent personnel from arbitrarily opening.
One copper bar is set in case of the invention, and indoor ground connection looped network draws two copper stranded conductors and is crimped to copper bar respectively, guarantees to connect
The reliability on ground.Closure is carried out using fire-proof mud between copper stranded conductor and cabinet.It is supported between copper bar and wall by insulator, while
The region for hanging button grounding clamp is reserved on copper bar.Ground terminal on copper bar fastens ground connection using WING NUTS and screw rod
Line, it is convenient and efficient.
The configuration of the present invention is simple is beautiful, and has very strong fire-proof waterproof anticorrosive ability.Reliably grounded connection is played to make
With WING NUTS need to only be turned by hanging when fastening is grounded, and be operated very convenient.
Other features and advantages of the present invention will then part of the detailed description can be specified.
