Product Description

General

HXGN15 series unit type SF6 ring net cabinet with SF6 load switch as main switch, for whole

cabinet is suitable for electric distribution automation and compact also expandable metal

close switchgear. It characters in its simple structure, flexible operation, reliable interlocking

and convenient installation etc., which can provide the satisfactory technical projects both for

different application occasions and users. With the adoption of sensor technology and the

protection relay up to date, plus the advanced technology and flexible assembly project,

HXGN15 unit type SF6 ring net cabinet can completely meet the requirement of continuously

variable market. It can take self-produced FLBS36 SF6 load break switch ; also according to

user's demand can be assembled with the internationally top-ranking VB4 series vacuum 

circuit breaker with permanent magnetic mechanism made by AREVA or HD4 type SF6 circuit

breaker made by AREVA or HD4 type SF6 circuit breaker made by ABB or with our VS1-12

type vacuum circuit breaker with permanent magnetic mechanism. Operational methods for

the main switch inside ring main unit can be either manual or electric power driven. And It can

meet the requirement of "Four Controls" when matched with FTU and RTU.

Main technical


Application
The HXGN15 is made up of modular units containing fixed or withdrawable metal-enclosed SF6

switchgear, using sulphur hexafluoride (SF6) or vacuum:

1) switch-disconnector;

2) VB4 vacuum circuit breaker;

3) JZ-10, or Rollarc 400 or 400 D contactor;

4) disconnector.

HXGN15 units are used for the MV section in MV/LV transformer substations in public
distribution systems and MV consumer or distribution substations up to 36kV

Operating conditions
.HXGN series units are designed for indoor installations

(IP2XC). Their compact dimensions are:

1) 375 mm to 750 mm wide;

2) 1600(1450, 1850) mm high;

3) 840(1200) mm deep...

this makes for easy installation in small rooms or prefabricated substations. Cables

are connected via the front.

All control functions are centralised on a front plate, thus simplifying operation.The units

may be equipped with a number of accessories (relays, toroids, instrument transformers,

surge arrestor, telecontrol, etc.)
