Low-smoke, halogen-free wires are made of rubber materials that do not contain halogens (F, Cl, Br, I, At), and do not contain lead, cadmium, mercury, mercury, etc., and do not emit toxic fumes when burned (eg hydrogen halide, Carbon monoxide, carbon dioxide, etc., will not cause secondary hazards, and meet the requirements of modern fire safety. The outer diameter of this kind of wire is smaller than the outer diameter of the whole PVC insulated wire of the same specification cross section. In the pipe construction, the pipe diameter can be reduced, or more wires can be worn under the same pipe diameter, and the construction installation cost can be reduced. . In addition, the wire product is much lighter than the PVC insulated wire product, which is easier to install and transport, reduce labor intensity and reduce transportation costs.

XLPE insulated wires can be rated up to 90°C for long-term operation and up to 250°C for short-circuit (maximum duration of 5S). The current carrying capacity is greater than that of PVC insulated wires. The minimum operating temperature of the cable is -15°C, and the minimum bending diameter is not less than the following: single-core cable: 20D (mm); multi-core cable: 15D (mm) (D: actual outer diameter of the cable).

Low-smoke, halogen-free wires have the following eight characteristics:

(1) Tensile strength is larger than general PVC wire: general PVC wire tensile strength is greater than 1.05Kgf/mm2, while low-smoke halogen-free wire tensile strength is greater than 1.2Kgf/mm2;

(2) Has good weatherability (-30°C ~ 105°C);

(3) It has non-shifting property (because there is no plasticizer added in the formulation of this product, there will be no shape shifting);

(5) No toxic black smoke will be produced when burning (a small amount of white smoke will be produced);

(5) It has a high volume resistivity: PVC wire is generally 1012~1015Ω/cm3, and low-smoke halogen-free wire is more than 1016Ω/cm3;

(6) Has good high pressure resistance: PVC wire is generally resistant to 10KV or more, and low-smoke halogen-free wire is up to 15KV or more;

According to different performance, low-smoke halogen-free wires can be divided into three types: ordinary, flame-retardant and fire-resistant.

(2) Description of fire-resistant wire and cable:

A refractory wire and cable is a cable that can be kept in normal operation for a certain period of time in a flame under specified test conditions.

1. According to the standard requirements of GB/T19216-2003 "Line integrity test of cable or optical cable under flame condition", the fire-resistant wire and cable must be burned at 750°C for 90 min, and the 2A fuse is not blown.

2. The fire-resistant wire and cable adopts a high temperature resistant organic fire barrier as a refractory layer. According to GB/T19666-2005, fire-resistant wire and cable can be divided into fire-retardant fire-resistant wire and cable and non-flame-retardant fire-resistant wire and cable. Flame-retardant refractory wire and cable mainly incorporates flame retardant in insulation or sheath to meet the flame retardant properties at the same time. Non-flame-retardant fire-resistant wire and cable is not added with flame retardant in insulation or sheath, it does not have flame retardant properties.

3. According to the test conditions specified in GB/T19666-2005, the flame-retardant wire and cable is divided into four grades: A, B, C and D.

FAQs

What are the disadvantages of halogen free cable? ›

Low Smoke Halogen Free Cable Drawbacks

This makes jacket less chemical/water resistant compare to non-LSZH cable counterpart. Jacket of LSZH cable experiences cracks during installation. Hence special lubricants are needed to prevent it from damage.

How do I know if my cable is halogen free? ›

If it is easy to ignite, you can be sure that the insulation layer of the cable is not made of low-smoke halogen-free material (probably polyethylene or cross-linked polyethylene material). If there is a large amount of smoke, it means that the insulating layer is made of halogen-containing material.

What is halogen free wire? ›

A cable is halogen-free if no halogens such as chlorine, fluorine or bromine are used in the cable's insulation and sheath material.

What is a low halogen cable? ›

Low smoke zero halogen cable considerably reduces the amount of toxic and corrosive gas emitted during combustion. When burned, a low-smoke zero halogen cable emits a less optically dense smoke that releases at a lower rate.

Does halogen free mean low smoke? ›

“Low-smoke” refers to the amount of smoke that a complete cable construction produces upon combustion. “Halogen free” refers to the amount of individual halogen elements (i.e., Chlorine, Bromine, Florine and Iodine) that are present in each combustible cable component.

Is halogen free mandatory? ›

This is not a government mandated process but a demand by environmentally-conscious consumers and groups to remove or at least reduce toxic materials from manufacturing processes where items like wires and cables, printed circuit boards, films, connectors, mechanical plastic parts and other items are made.

What is the difference between halogen free and LSZH? ›

Typically, a halogen-free cable is made of polypropylene, which does not produce a dangerous gas or acid in fire conditions. Cables intended to fulfil this type of function are often referred to as one of the following: LSZH – Low Smoke Zero Halogen. LSOH – Low Smoke Zero Halogen.

Are PVC cables halogen free? ›

No. A cable with a PVC outer jacket cannot be halogen-free. The abbreviation PVC stands for polyvinyl chloride. The chloride (or chlorine) is a halogen.

What is the difference between halogen free and flame-retardant? ›

Unlike traditional flame retardants, HFFRs do not contain halogens such as chlorine or bromine, making them more environmentally friendly and less harmful to health. These special additives react during a fire by absorbing heat and slowing down or suppressing the spread of flames.

Where to use low smoke cable? ›

More prescriptive regulations govern the use of LSZH cable jacketing in specific industries. Fire resistant cables are widely used in aircraft, trains, ships, submarines, tunnel systems, nuclear power stations and much more. EU regulations require their use in a wide variety of network cables.

What are the benefits of Low Smoke Zero Halogen? ›

Improved fire safety: As mentioned above, LSZH cable emits significantly less smoke than PVC cable. This can make a big difference in a fire situation, giving occupants more time to evacuate safely. Reduced risk of toxic fumes: In addition to smoke, PVC cables can also emit toxic fumes when burned.

What are the disadvantages of LSZH cable? ›

Disadvantages
  • Because LSZH is more susceptible to jacket cracking caused by pulling lubricants or cable bending, special lubricants1 have been developed to minimize cable damage during installation.
  • LSZH jacket compounds usually have very high filler content (approx.

What are the bad things about halogen lights? ›

Because of the very high temperatures, halogen lamps can pose fire and burn hazards. In Australia, numerous house fires each year are attributed to ceiling-mounted halogen downlights.

What is the difference between halogen free and flame retardant? ›

Unlike traditional flame retardants, HFFRs do not contain halogens such as chlorine or bromine, making them more environmentally friendly and less harmful to health. These special additives react during a fire by absorbing heat and slowing down or suppressing the spread of flames.

Does halogen use more electricity? ›

How many lights are in your home and how long they are switched on will impact on your electricity bill. LED bulbs can use anywhere from 7-20 watts per hour, whereas halogens use anywhere from 35 to 500 watts an hour to emit the same amount of light, which makes LEDs are much cheaper to run.
