Environmentally Friendly Low Smoke and Zero Halogen(LSZH) Production Line

2018-08-27

cable wire production line

With the high requirements of safety and environmental protection, more and more wire companies are entering the halogen-free field.

LSZH retardant polyolefin insulated wire is suitable for AC rated voltage of 450/750V and below. It is required to be used for fixed laying of the electrician, telecommunication equipment, instrument, power device and lighting circuit in flame retardant occasions,made of copper and environmentally friendly flame retardant polyolefin, the performance indicators of the products are in line with national standards. It has the characteristics of acid and alkali resistance, oil resistance, moisture resistance and mildew resistance,mainly divided into ordinary, flame retardant, fireproof.

LSZH wire doesn't contain any toxic substances or generate a large amount of smoke when burned. If unluckily a fire occurred, the spread speed is slow, the smoke concentration is low, and the amount of harmful gas released small, which is convenient for personnel to evacuate during a fire. The combustion gas is less corrosive, avoids damage to the equipment, low-halogen, halogen-free characteristics, and also greatly improves the cable aging resistance and UV resistance and other radiation performance, thereby extending the service life of the cable. LSZH cable is made of a rubber material that doesn't contain halogens (F, Cl, Br, I, At), or lead, cadmium, chromium, mercury, etc., even generate emit toxic fumes when burned (eg: Hydrogen halide, carbon monoxide, carbon dioxide, etc.), which will not cause secondary hazards and accord with modern fire safety requirements. The outer diameter of this kind of wire is smaller than the outer diameter of the whole PVC insulated wire in 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, which makes the coat of construction installation reduced. In addition, the wire product is lighter than the PVC insulated wire product.

Main features of LSZH wires:

(1)The tensile strength is larger than that of the general PVC wire( the tensile strength of the general PVC wire is greater than 1.05Kgf/mm2, and the tensile strength of the low-smoke halogen-free wire is greater than 1.2Kgf/mm2)
(2) Good Weather Ability (-30 ° C ~ 105 ° C);
(3) Good Softness (hardness 80-90)
(4) 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);
(6) High Volume Resistivity ( PVC wire is generally 1012~1015Ω/cm3, and low-smoke halogen-free wire is more than 1016Ω/cm3 )
(7) Good High Pressure Resistance (PVC wire is generally resistant to more than 10KV, while low-smoke halogen-free wire is up to 15KV or more)
(8) Good Elasticity and Viscosity

Pelletizing line for rubber and plastic


Guangdong LINA LSZH cable material modification granulator combines mixing, conveying, feeding, extrusion granulation, cooling, screening and storage. It also realizes automatic continuous operation, high production efficiency, good plasticizing and mixing effect, compact structure, small footprint and space, and can be used for flat device, mixing, feeding, extruder, etc., which can be operated independently and in linkage. The production process is divided into closed-loop temperature control, the temperature control is stable, the material is evenly fed, and the granules are full. It is especially suitable for materials with high mixing requirements and direct extrusion of aggregate materials. The electronic control system adopts advanced PLC control technology to make multi-machines such as feeding, extrusion and pelletizing high precision and wide linkage according to process requirements, and operates with full machine chains, sound and light fault alarm and self-protection.
