THE FUNCTION OF INSULATORS

A lot of disc-shaped insulators are hung at one end of the high-voltage wire connection tower. It is to increase the creepage distance. It is usually made of glass or ceramics, which is called an insulator. In order to prevent dust and other contaminants from adhering to the surface of the insula... Read More

COLD SHRINK TERMINAL

The cable joint is also called the cable connector. After the cable is laid, in order to make it a continuous line, each segment of the line must be connected. The cable joints in the middle of the cable line are called intermediate joints, and the cable joints at both ends of the line are called... Read More

THE FUNCTION AND CHARACTERISTICS OF YJV CABLE

YJV cable is a commonly used type of power cable. Nowadays, many people refer to YJV cable when talking about cable. As the backbone cable in power transmission, YJV cable is like the arterial blood vessels in human blood vessels, or the trunk of a tree, which shows its important position in powe... Read More

WHY DO THE POWER CABLES HAVE MANY LAYERS？

Power cables are relatively common cables for distributing and transmitting electrical energy. They are usually used in urban underground power grids, internal power supply in industrial and mining enterprises, and so on. People who have some knowledge of cables will find that power cables have m... Read More

DAILY MAINTENANCE AND REQUIREMENTS OF OIL-IMMERSED POWER TRANSFORMER ON-LOAD TAP-CHANGER

1. Before the on-load tap-changer is put into operation, it should be checked whether the oil level is normal, there is no oil leakage, and the control box should be well-proofed from moisture. 2. After the newly commissioned on-load tap-changer gas relay is installed, the operator should release... Read More

WHAT IS THE INSULATION EFFECT OF THE HEAT SHRINKABLE SLEEVE IN PRACTICE?

The efficacy of insulating heat shrinkable sleeves The most critical function of insulating heat shrinkable sleeves is of course insulation maintenance. The efficacy of heat shrinkable sleeves is very common: anti-corrosion, acid and alkali resistance, anti-electricity (insulation), and anti-leak... Read More

APPLICATION OF SF6 LOAD SWITCH IN DISTRIBUTION NETWORK

Application of SF6 Load Switch in Distribution Network The medium-voltage switches used in general hub substations all use circuit breakers as control and protection devices, and must have automatic reclosing. However, the power supply capacity of each power distribution station in the ring netwo... Read More

PERFORMANCE COMPARISON OF SF6 COMBINATION APPLIANCE AND CIRCUIT BREAKER

Performance Comparison of SF6 Combination Appliance and Circuit Breaker Breaking no-load transformer performance Most of the load properties of the ring main unit in the power distribution system are the splitting and closing of the distribution transformer. The general capacity is 315-1250 kVA, ... Read More

PERFORMANCE CHARACTERISTICS OF SF6 LOAD SWITCH + FUSE COMBINATION

1) The load switch that uses SF6 gas as insulation and arc extinguishing medium is called SF6 load switch. It can be used for making and breaking load current, as well as making and breaking no-load lines, no-load transformers and capacitor banks. 2) SF6 load switch can close short-circuit curren...

WHAT ARE THE ADVANTAGES OF XLPE INSULATED POWER CABLES COMPARED WITH ORDINARY POWER CABLES?

1. First of all, the most intuitive point is that the insulation materials of XLPE insulated power cables and PE insulated power cables are different. 2. Compared with ordinary power cables, XLPE insulated power cables have better temperature resistance, and their temperature resistance levels ca... Read More

10KV COLUMN LOAD SWITCH

The load switch on the column has the capacity of carrying and breaking the rated current, but cannot break the short-circuit current. It is mainly used for line segmentation and fault isolation. (1) Gas-producing load switch. The gas-generating load switch is to use the slit composed of solid ga... Read More

APPLICATION RANGE OF POWER CABLE AND ITS ADVANTAGES

Cables can be divided into: power cables, control cables, communication cables, radio frequency cables, constant temperature cables, temperature control cables, etc. Power cables transmit and distribute high-power electrical energy. Above 35 kV are called medium and low voltage cables, or power d... Read More
