Cross-linked the XLPVC XLPE wires features

Cross-link wire and cable changes insulation molecular structure. XLPE and XLPVC are made by forming strong chemical bonds using electron beam radiation. This bond does not melt or brittle at high temperature, pressure, or mechanical stress like other polymers. This creates an insulator that holds its form at high temperatures and protects the conductor from severe conditions. The electrical qualities and low moisture absorption rate of XLPE make it popular for power cables and car cross-link wire. Cross-linking and flame resistance make XLPVC an ideal panel and enclosed area material. Both variants outperform PVC in oil, chemical, and solvent resistance. They are flexible even at freezing, which is great for outdoor and automobile applications.

UL4413 is good for low voltage portable power applications.

Which Materials as wire insulation can be used for Cross-link

Cross-linking is not possible for all plastics. The most successful materials are those which respond well to chemical or radiation treatments. Choose from three leading materials to customize the insulation to the needs of your particular application; XLPE, Irradiated LSZH and Irradiated PVC. Each of these materials adds its own unique characteristics to the finished cross-link wire and cable.

XLPE / Irradiated PE

XLPE, or cross-linked polyethylene, is used as insulation material in high-performance cables. Normal PE is modified into a thermoset material which will not melt when exposed to electron beam radiation. Excellent electrical insulation is maintained even at temperatures as high as 125°C. “XLPE is resistant to moisture, ultraviolet radiation and most chemicals making it ideal for use outdoors, underground and in automobiles.”

LSZH Irradiated

LSZH is a low smoke zero halogen product. By exposing it to radiation, it gets the cross-linking thermal strength and the benefit of fire safety in that it emits very little harmful smoke. That is why it is the material of choice in highly flammable environments such as subways, trains, ships and public structures. Irradiated LSZH cables are not only flexible and durable, but also meet stringent fire performance requirements.

Irradiated PVC

Regular PVC gets soft and flows when it is heated. But the cross-linking that takes place in irradiated PVC makes it unique. It retains its solid form at high temperatures. PVC is already known for its flame retardancy and low cost, and now has added improved heat resistance and cut-through strength. Irradiated PVC finds application in many fields where a compromise between cost and performance is necessary, e.g. appliance wiring and automotive harnesses.

Advantage of the Cross-linked a wire insulation

Rated temperature to 125C℃

Most wires have insulation that starts to degrade and eventually breaks down at temperatures between 70° and 90° Celsius. When the wire is cross linked the molecular bonds hold it together even at 125 ° C. So you can get more current through the cross-link wire and cable without damaging it. Industrial ovens, control panels, engine compartments and the like demand extreme heat resistance. This is possible by cross-linking.

Fire-proof and Flexibility

Cross-linked cable insulation chars instead of dripping when exposed to fire. It burns slowly and so fires are less likely to spread along the length of the cable. Also, cross-linking does not make the wire rigid, but on the contrary, it keeps it flexible even in cold temperatures. In an emergency you get a wire that is fire-resistant and can be bent and routed quickly during installation. That strange combination is ideal for vehicle cross-link wire and building wiring.

Abrasion proof

Wires in moving machinery, cars and narrow conduits have a trouble with constant rubbing. When the normal insulation is worn through, the conductor is exposed. The thick molecular network of cross-linked insulation fights back against cuts, scrapes and surface wear far more effectively than plain old PVC or PE. This abrasion resistance will directly result in fewer problems, less maintenance, and a longer lifespan.

Indústrias e aplicações

Automotive & EV

Many newer vehicle harnesses have automotive cross link wire or cross link automotive wire as their standard. They stay perfect and intact throughout the life of the car, even with exposure to gasoline, high temperatures and constant vibration from the engine.

Power Distribution & Utilities

Electron beam cross-linked cables are used for power grids, substations and distribution networks. Their high current capacity and thermal stability improve grid dependability at long distances and reduce energy loss.

Máquinas industriais

In factories the cross-link wire and cable is used in motors, drives and control panels. The abrasion-resistant insulation can withstand high temperatures, constant movement and oil in the machinery without being damaged.

Aerospace & Defense

Aerospace wiring must have thin, tough insulation that is sensitive to weight. Irradiated materials and cross-linked XLPE are providing the best weight-to-performance ratio for drones, military vehicles and aircraft.

Marine & Rail

Cross-link wire and cables irradiated with LSZH are required to comply with fire safety regulations for ships and trains. These wires will emit very little smoke, and no harmful gasses, protecting passengers and crew in the event of a fire.

Energias renováveis

The sun’s energy, rain, salt air and wildly changing temperatures could turn wind turbines and solar panels into power. The insulation life of XLPE cross-linked cables is 25 years or more and all these stresses can be sustained without any deterioration.

Better Option than Primary Wires

  • Cross-link wire can be used up to 125°C, while typical primary wire is rated for only about 80°C. This makes cross-link wire suitable for use in hot engine bays.

  • The molecular network of the cross-linked main wires can resist wear in abrasive conditions and last three to five times longer than standard insulation.

  • When exposed to fire, cross-linked insulation burns and extinguishes itself, while regular main wire melts and drips, setting everything in its path on fire.

  • Cross link wire is rated the same but occupies less diameter so the insulation can be thinner. This leads to savings in weight and space in dense wiring packages.

  • Primary wire deteriorates quickly with repeated chemical contact, secondary wire more resistant to oils, coolants & solvents generally found in industrial & automotive areas.

  • Cross-link wire and cable remains elastic to -40°C. On the other hand, winter installation can make a number of main wire types brittle and crack.

  • Improved current carrying capacity for the same gauge- improved thermal management allows one to step down wire gauge and still meet electrical demands.

  • Fewer replacements, less downtime and fewer warranty claims.

Electron Beam Cross-Linking Basics

An electron beam crosslinker is the cleanest, most precise means to cross-link wire and cable today. This method treats extruded wire in a high-energy electron accelerator. Electron beams are sent deep into the insulating layer at nearly the speed of light. They disrupt molecular bonds within the polymer, forming new crosslinks between chains. The result is a three-dimensional thermoset network. Insensitive to heat and flow. 

Electron beam cross-linking allows exact density control without byproducts or additions, unlike chemical cross-linking. It's used for automotive, aeronautical, and medical EBX cables. The quick procedure on continuous lines simplifies mass production. Maintaining wall thickness within a set range ensures regular cross-linking across the insulation as the beam penetrates from the outside in.
