VS1-12 High Quality Indoor Fixed type VCB

By pdtblogger
In order to meet the market requirements for high quality VS1 as well as their adaptation with its switchgear, Jigao High Voltage Company develops this new generation of VS1 type indoor high voltage vacuum circuit breaker. It is three- phase AC, 50 Hz indoor power distribution equipment with the voltage of 12kV. It can be used for protecting and controlling equipments in the fields of power supply and distribution system such as substation and industrial and mining industry etc.

VS1 series vacuum circuit breaker has taken into consideration of reliable interlock function which can be frequently operated at the ratedcurrent and with the capability of many times operations of breaking short-circuit current and fault current. This series of vacuum circuit breaker is an integrated unit by adopting the front and rear arrangement between operating mechanism and vacuum interrupters technology. It can be used for fixed installation unit and also can be used for independent track by equipped with Chassis.

Product Standard


VS1 type vacuum circuit breaker conforms to national standard GB 1984-2003 HV Vacuum Circuit Breaker, JB3855-1996 3.6- 40.5kV indoor AC high voltage vacuum circuit breaker, DL/T403-2000 12kV 40.5kV HV vacuum circuit breaker ordering technical conditions, and IEC62271-100:2001 high voltage AC circuit breaker relevant regulations.

Applying Ambient Conditions


  1. Ambient temperature: -10℃–+40℃
  2. Ambient humidity: the average humidity of a day should be no more than 95%; the average humidity of a month should be no more than 90%;
  3. Earthquake intensity: not exceed 8 degrees
  4. Saturated vapor pressure: average pressure of a day should be no more than2. 2kPa,the average pressure of a month should be no more than 1.8kPa;
  5. The height above sea level: 1000m(not including special requirements)
  6. It should be installed in the places without fire, explosion, serious filth, chemical corrosion and violent VS1 ration.
For use in an environment prone to chemical corrosion, reclosers by this company (TES) are perfect, but for medium-voltage networks.

How Forklift Fleet Management Systems Can Bring Flexibility & Agility to Your Supply Chain

By pdtblogger
Important lesson that has risen to the top is the precarious balance between supply and demand and the potential danger of having a supply chain that is too lean. While there are benefits to a lean approach, the pandemic has shown the limitations that could occur as many supply chains were caught off-guard, lacking the flexibility and agility to quickly react to changing market demands and conditions. Many companies struggled to get their supply chains back on track, with some still confronting challenges as we entered the holiday shipping season. There are a number of strategic steps you can take to enhance your supply chain with greater flexibility and agility. When it comes to your material handling equipment needs, the best step you can take is implementing a forklift fleet and operator management system. When utilized effectively, the right system can guide and inform an approach that increases flexibility and agility while helping maintain lean principles and identifying o...

Circuit Breakers Breaking Capability - Right Calculating According to Existing Operational Model

By pdtblogger
Each circuit breaker has its own name plate, we shall find auto recloser sequence, O-C-O with time sequences, for distribution systems auto recloser may have two trials, auto recloser is leading into chock of power system but improves system reliability up to the limit that “it would not me notified by operator, but by monitoring systems, cables in Middle East wouldn’t be provided with auto-recloser, it is only for overhead lines up to MV level where most of faults are transient. We shall find “normal operating current” which is the full rating current “ for 220kV breakers 2500 AMPS” , breaking current capability, which is withstand capability for short circuit, it is 40 or 50 KA for 220KV network, and making current capability which is 2.55 times capability withstand, there were some papers talking about figures close to 3 times, mostly not applied because of higher cost, making current for 40KA is 100KA, for 50KA, it shall be 125KA.

Crown Forklift Battery Maintenance Tips

By pdtblogger
The biggest headache in any operation is downtime. When not properly maintained, batteries can cause forklift downtime for charging, maintenance or even replacement. Proper maintenance of your forklift batteries and chargers is crucial to keeping your operation up and running. Forklift Battery Hazards and Problems Weak or Bad Cell - An undetected weak or bad cell will cause more battery changes and overheating, shortening the life of the battery for your forklift or lift truck. Corrosion - A dirty or corroded battery creates heat buildup that can decrease run time, shorten the battery’s life, and lead to other significant safety hazards. Damaged Cables - Damaged cables and connectors increase maintenance costs due to false voltage and amp readings, causing intermittent codes and diagnostic problems. Improper Charging - Improper charging practices can increase charging frequency and shorten the life of your battery. When You Install or Change a Battery Turn the truck OFF and c...
