Low-smoke and zero-halogen power cables can also be called environmentally friendly cables, and low-smoke and halogen-free cables are mostly used in important occasions with high environmental requirements. Low-smoke halogen-free cables generally use red copper wire as the core. In the event of a fire, the wire sheath can continue to be energized to transmit data to avoid data loss, and when it burns, it does not drip and has no black smoke. 30% chance of escape. Low smoke zero halogen has the following five characteristics:  1. Zero halogen:  The use of environmentally friendly insulating layer, sheath and special oxygen barrier materials not only have good electrical and physical and mechanical properties. It also ensures that the product does not contain halogen and solves the "secondary pollution" formed when it is burned. It avoids carcinogenic "dioxin" substances produced when traditional PVC wires are burnt. 2. High flame retardancy: The halogen-free low-sm...

1. Copper Or Aluminum Monofilament Drawing Commonly used copper and aluminum rods for wires and cables , at room temperature, use a wire drawing machine to pass through one or several stretch die holes to reduce the cross-section, increase the length, and increase the strength. Wire drawing is the first process of various wire and cable companies. 2. Monofilament Annealing Copper and aluminum monofilaments are heated to a certain temperature to recrystallize the toughness of the monofilament and reduce the strength of the monofilament to meet the requirements of the wire and cable for the conductive core. The key to the annealing process is to prevent the oxidation of the copper wire. 3. Stranding Of Conductors In order to improve the flexibility of the wire and cable and facilitate the laying and installation, the conductive core is made of multiple monofilaments twisted. From the stranding form of the conductive core, it can be divided into regular stranding and irregular stranding. ...

Cable insulation is a non-conductive material, or a material that resists the flow of current. It is often referred to as the dielectric in radio frequency cables. The insulation layer can prevent leakage, prevent the current of the wire from contacting other conductors, and protect the material integrity of the wire by preventing environmental threats such as water and heat. The safety and effectiveness of wires depend on their insulation. The following is a brief description of fluoropolymer insulation and provides information on the typical uses, advantages and disadvantages of each option.   Fluoropolymer Polyvinylidene fluoride The rated temperature range of PFA is 250°C to 65°C. It also has a very low dissipation factor, making it an electrically efficient choice. It is not thermoset, so it can only be used in specific applications. Although PFA can be processed for a long time, it is also an expensive material. Polytetrafluoroethylene (PTFE) PTFE is a thermoplastic materia...

XHHW is a letter or abbreviation, which means "XLPE (cross-linked polyethylene) high heat and water resistance". XHHW is the name of specific insulating materials, temperature grades and conditions of use (applicable to humid places) for wires and cables. Wires with XHHW insulation are commonly used in alternating current (AC) power distribution systems in commercial, public institutions, and industrial buildings and facilities, usually at a voltage level (potential difference or electromotive force) of 110-600 volts. This insulation can be used for solid or stranded copper and aluminum conductors, depending on the size. According to Underwriters Laboratories (UL) Standard 44, XHHW insulation materials are suitable for use in dry locations up to 90°C (194°F) or wet locations up to 75°C (167°F). XHHW -2 insulation material is similar to XHHW, and is suitable for dry or humid places with a maximum of 90°C (194°F). The insulation of XHHW / XHHW-2 electrical conductors is subject...

  With the rapid development of the communications industry in recent years, cable products have also developed at an astonishing speed. The use of cables has also been greatly improved and is flexible. The cable can be coiled on the cable reel with a bending radius ≥ 20D, and D is the outer diameter of the cable. The fire-fighting cable is smokeless and non-toxic when burned, and the insulating material is inorganic material "non-combustible". It will not produce harmful gases during combustion, and will not cause secondary pollution. It is called an environmentally friendly green product. The safety is good. In addition to the normal power supply, the fire-fighting cable can start the fire-extinguishing equipment in the flame to reduce fire losses. At the same time, it is particularly reliable for personal safety. The copper sheath is a good conductor and the best grounding wire, and it continues to the full length of the cable, which greatly improves the sensitivity and r...

Additional cool assistance, Uneven contact, Poor sealing, Low installation efficiency, Increased installation costs. Are these your pain points? Let us give you a way out.

You don't need hot or special tools, no open flame,no heating when installation, so it is safe and reliable. Also it is save time and effort, just pulling wire core, elastomer ...

Are you still worried about the rotation of the cable connected to the distribution cabinet and the friction with the distribution box to reduce the service life of the cable? Now, a  solutio n is here. Cable gland s , one of the types of cable accessories ,    plays a vital role in cable laying . The main function is to tighten and seal the cable. Tightening means to lock the cable through the gland, so that the cable does not produce axial displacement and radial rotation, so as to ensure the normal connection of the cable. Sealing refers to the IP protection -  dustproof and waterproof . Typical application examples . With the increasing variety of cable accessories, it also brings challenges and opportunities to the entire wire and cable industry . For example,   In the process of cable laying, the wires entering the power distribution cabinet must not only be fixed, but also reduce the friction caused by between the cable and the power distribution cabinet ...
