Cables: What factors affect the lifespan of rubber sheathed cables?
Today, electricity is widely used in our country. Rubber sheathed cables have penetrated all walks of life. The service life of cables directly affects production safety. The service life of cables depends on the oxidation induction time of the sheath material. The design service life of rubber sheathed cables is generally 20 years, but the actual service life is much longer. The most direct cause of cable aging is damage to the insulation layer. Many factors can lead to reduced cable insulation. Based on practical operating experience, the following situations are summarized. 1. Insufficient moisture resistance This situation is also common, usually occurring when directly buried in pipes or at cable joints. For example,

Cable: What do the colors on the wire and cable mean?
Everyone knows that the wires inside a cable have different colors. What are these colors for? Let me introduce the meaning of the colors on the cable below. Cable Sheath Color Regulations for Cable Conductor Sheath Colors National Standard: Yellow, green, red, and blue represent a, b, c, and n. When the circuit is marked by the color of the conductor: 1.1 Black: Internal wiring of devices and equipment. 1.2 Brown: Positive pole of DC system circuit. 1.3 Red: Three-phase circuit and C phase

Cable: Identification of low-smoke halogen-free power cables
Low-smoke halogen-free power cables, also known as environmentally friendly cables, are mostly used in hospitals and places with strict environmental hygiene requirements. The identification of low-smoke halogen-free power cables mainly lies in the identification of insulation materials. Based on different materials, it can be determined whether it is easy to burn, and whether it is a flame-retardant wire - ZRBV or a flame-retardant power system cable - ZRYJV... According to whether the enterprise has combustion, the color of the flame is identified; whether it smokes, and how much smoke is produced to analyze and judge whether it is a low-smoke halogen-free power engineering cable - WDZ-YJV. If so, identify the color of the smoke, such as: whether the smoke is clear smoke or...

Cable: Grounding methods for steel wire armored cables
The grounding map of steel wire armored cable refers to a cable with a ring and different armored protective layers. In addition to the bending life of the equipment, the armored cable should also have smooth tensile and compressive strength, and consider obstacle factors to reduce the anti-interference characteristics of the cable. The armor used is different from steel strip, steel wire, aluminum strip, and aluminum pipe. Among them, steel strip and steel wire armor have high magnetic permeability and can be used for magnetic shielding. The reason why it can effectively resist low-frequency interference is that the steel wire armored cable can be directly buried in the map, and it is also free from pipe laying, and it is also cheap and good. The reason why the steel wire armored cable grounding map can be placed in the equipment and protective layer is

Cable: Some advantages of flexible fire-resistant cables
Speaking of cables, many researchers have encountered them in our daily learning and living environment and need to use them frequently. They are devices used for transmitting power quality or signals, generally consisting of several wires or groups of wires, appearing rope-like in appearance. Moreover, each group of wires has a mutual insulation effect, often effectively twisted around a central core, with the entire exterior covered by a thick, highly insulating layer, featuring internal conductivity and external insulation. Today, I will lead everyone to understand and analyze some of the main advantages of flexible fire-resistant cables, helping to improve...

Low-smoke halogen-free cable: How to identify a low-smoke halogen-free cable?
What are the identification methods for low-smoke halogen-free cables? 1. Product name identification method for low-smoke halogen-free cables. Low-smoke halogen-free flame-retardant polyethylene insulated wires and cables, low-smoke halogen-free flame-retardant polyethylene insulated, low-smoke halogen-free flame-retardant polyethylene sheathed power cables. Counterfeits generally have slight differences, such as polyethylene insulated low-smoke halogen-free sheathed flame-retardant power cables. 2. Skin burning method for identifying low-smoke halogen-free cables. When ironing the insulation layer with an electric iron, there should be no obvious dents. If there are significant dents, it indicates that there are defects in the materials or processes used for the insulation layer. Or use a lighter to bake, generally should not

Mineral cables: Common causes of wire and cable failures
It is understood that the direct cause of wire and cable failures is the reduction and breakdown of insulation capacity. There are many factors that lead to the reduction of insulation sensitivity. Based on the practical operation and management experience of enterprises, the following different situations are summarized. Hongsheng Wire and Cable Co., Ltd.'s editor will take you to understand. 1. External damage. 2. Insulation moisture. For example: unqualified wire and cable connectors, in humid climates, joints can produce water or water vapor, under the action of the electric field for a long time, layered water tree mixing, gradually reducing the insulation strength, causing damage to the cable failure.

Copper core wire: Characteristics of copper core wire
Currently, all wires on the market use copper core wires, far exceeding aluminum core wires. Why is the market share of copper core wires so high? Jindi Cable claims the advantages of using copper core wires. 1. High strength: The allowable stress at room temperature is 7~28% higher for copper core wires than for aluminum wires. The difference is even greater at high temperatures.

Why are some wires not covered with insulation?
You may have noticed that some power lines are bare! So will such power lines cause electric shock? In fact, "bare" high-voltage lines are very common, and industry insiders call them "bare wires." However, since someone asked, we think it is necessary to explain it again. Why do some high-voltage power lines "run naked"?
