Outdoor 36kV GCB SF6 Gas Circuit Breaker Substation Type With Long Service Life
Quick Detail: Indoor high voltage vacuum circuit breaker
DINGLI strives to bring our customers the latest technology and competitive pricing and best service for distribution
automatic GCB medium voltage circuit-breakers for outdoor installation use sulphur hexafluoride gas (SF6) to extinguish
the electric arc and as the insulating medium. Breaking in SF6 gas takes place without current chopping or generation
of overvoltages. These characteristics guarantee a long electrical life for the circuit-breaker and limited dynamic di-electric
and thermal stresses on the installation.
The GHS type of stored energy and free release mechanical operating mechanism allows opening and closing operations
through local and remote control. The operating mechanism, the activating kinematics of the moving contacts and the
anti-condensation heater are located inside a tight metal enclosure which also acts as the support for the poles. The
above-mentioned structure is supported by a frame made of telescopic metal sections which allow the height of the
circuit-breaker terminal to be adapted from 2800 mm to 3700 mm.
The metal enclosure has IP 54(*) degree of protection and is fitted with a tight door with an inspection window.The
circuit-breaker is compact and ensures a high level of sturdiness and excellent mechanical reliability.The enclosure
is made out of a steel plate with adequate surface protection by a special metalising and painting process. The support
structures are hot dip galvanised.
Main Contact Separation
No electric arc is struck because the current flows through the arcing contacts. During its run downwards,
the moving apparatus compresses the gas in the lower chamber. The compressed gas flows from the lower to
the upper chamber. hereby taking both the chambers to the same pressure.
Arcing Contact Separation
The current flows due to the electric arc which has struck between the arcing contacts. The gas cannot escape
through the nozzle because the hole is still closed by the fixed arcing contact and cannot even escape through
the inside of the arcing contact, because of the clogging effect of the electric arc.
Standards And Service
The GCB circuit-breakers comply with the IEC 62271- 100 standard as well as of other major industrialised countries.
They have undergone the tests indicated ensure service safety and reliability of the apparatus in alll installationsThe
mechanical and electrical locking devices have been provided to prevent incorrect operations and to carry out nspection
of the installations while guaranteeing maximum operator safety.
1. Specific packaging can be made to order.
You can specify other shipping methods such as Airmail, FEDEX or DHL. We shall let you know about the
shipping cost after receipt of your order.And also can send by sea or air, kindly send me the port of yours.
The standard procedure for making wooden case is as follows:
Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100
engineers. We have special pre-sales engineer to work with customer at early stage of the project.
Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia, Peru,
Ecuador, Senegal, which will make a fast response for customer.
Clients of Bolivia visited Dingli for factory inspection, we talked about the key issues faced right now, and found
ways to solve it together. They set a high value on this cooperation.
