(1) After opening the switch, establish a reliable insulation gap and separate the equipment or line to be repaired from the power supply with an obvious disconnection point to ensure the safety of ma ...

For circuit breakers with stable mechanical properties, the peak values ​​of the opening and closing vibration waveforms and the time difference between the peak values ​​are relatively stable. The ba ...

Wall Switch can't stand the erosion of time, which will cause repeated power outages, and the sockets will become hot and hot. In a particularly serious moment, it will directly cause the electrical a ...

Cold Shrink Cable Accessories needs to be pre-checked before installation, and the quality of each point is checked from beginning to end. The rubber used for cold shrink has the characteristic of "el ...

drop out fuse has the best heat dissipation effect when installed horizontally. An inclination angle of more than 15° will lead to uneven pressure distribution inside the arc extinguishing tube and a ...

For example: In a double bus circuit, High Voltage Disconnect Switch can be used to switch the running circuit from one bus to another bus. At the same time, it can also be used to operate some small ...

Online detection of mechanical characteristics, Power distribution cabinet monitoring contents include: closing and opening coil circuit, closing and opening coil current, voltage, circuit breaker mov ...

Nowadays, the copper sheet structure inside the Wall Switch socket of inferior hotels is very unreasonable. The material used is not only rough and thin, but also easy to rust. As a result, the plug w ...

Cold Shrink Cable Accessories generally uses silicone as the insulating material, which is hydrophobic and easy to slide off when there are water droplets or moisture on it, and has UV resistance. ...

Ambient temperature compensation ‌ For every 1°C increase in ambient temperature, the continuous load capacity of drop out fuse will decrease by 0.5% to 0.8%. In plateau areas (altitude > 1000 mete ...

It may cause arcing (phase-to-ground or phase-to-phase short circuit), burn equipment, and endanger personal safety. This is the so-called "load-pulling High Voltage Disconnect Switch" serious acciden ...

Opening and closing faults: This type of fault is caused by the circuit breaker body. For low-oil circuit breakers, it mainly manifests as oil injection short circuit, arc extinguishing chamber burnin ...

Wall Switch The location must be standardized. When installing wall sockets, most families think that it will be unsightly if the sockets are too high, so they will install them in relatively low and ...

Compared with prefabricated cable accessories, although Cold Shrink Cable Accessories relies on elasticity to ensure internal characteristics, it has many types and specifications, and is very diverse ...

In the case of instantaneous impacts such as motor starting, drop out fuse needs to be able to withstand a short-term overload capacity of 6 to 8 times the rated current. The design needs to be combin ...

The contacts of High Voltage Disconnect Switch are all exposed to the air and have obvious disconnection points. The high-voltage disconnector has no arc extinguishing device, so it cannot be used to ...

Survey statistics show that the main types of Power distribution cabinet faults are as follows: (1) Refusal to operate and malfunction: This type of fault is the most common fault in high-voltage swit ...

Never use the same hotel Wall Switch with multiple electrical appliances. This will overload the electrical appliances and may cause a major fire. Air conditioners, range hoods and other electrical ap ...

Compared with heat shrink cable accessories, there is no risk of internal accessory layers coming apart when moving or bending after installation, as with heat shrink cable accessories, because Cold S ...

Rated current and continuous load The load of continuous operation of drop out fuse mainly depends on its rated current parameters. Taking RW11 as an example, its rated current range is usually 10A-20 ...

High Voltage Disconnect Switch is mainly used to reliably isolate the part of the high-voltage distribution device that needs to be shut down from the live part to ensure the safety of maintenance wor ...
