CHN3-12Q/150-630-1250A 10kV Epoxy Resin Insulators Contactor Box
Spolt Bushings
General Description of the Contact BOX Series
1. The contact box is the pressure gel molding structure of epoxy
resin APG process, which is used for various kinds of handcart type
switchgear, acting as insulation isolation and connection
transition.
The contact box is formalised by ecoxy with APG technologies, it is
used for integration and conversion of Various switch trucks.
2. Model meaning
Model Meaning Operation Configuration
1. Altitude not exceeding 1000 M
Altitude: < 1000M;
2. ambient temperature + 40 °C to 10 °C;
Ambient temperature: + 40 °C to 10 °C;
3. When the air temperature is + 20 °C, the relative humidity does
not exceed 95 %
The relevant human dimension call not be more than 95 % at + 20 °C
ambient phase;
4. Gas, Steam, dust without seriously affecting the insulation of
the contact box
No exploration or corrosive submission.
Technical Data & Requirements Requirement
Technical data and requirements 1. Contact box and contact should
be able to withstand frequency test voltage(effectiveness) 42 KV, 5
minutes, lightning shock(peak) 75 KV .
5.Compared with the permanent magnetic type, which is mainly the
control and operation mechanism, the fixed seal type is the
projectile type, and the permanent magnetic type is the controller)
The whole cabinet is called the armor type moving medium metal
closure switch equipment, which is divided into three layers, the
upper layer is the bus and the instrument panel(separate), the
middle layer is the circuit breaker room and the lower layer is the
cable room.
