automotive wiring harness Conduit

PREFERENCES

They are very light, which makes it easier to assemble and transport them.
• They have excellent mechanical and physical features
• They are resistant to impact, as well as impermeable to water and dust
• They are long lasting, and without need for maintenance
• flexible pipes make possible continuous placing and are very adaptable to the demands of the terrain; also these pipes are very cost saving.
• they are used at temperature range from -40°C up to +80°C
• they are highly resistant to corrosion• Light material, easy and quickly to storage and manipulate
• Easy to transport, simple and cheap assembling process
• The process of connecting two PVC pipes doesn’t last for more than 1 minute, there for the interruptions of the traffic do not last very long
• They have thin walls, so that the laying of the cables inside the pipes is very swift and simple
• In the same trench a large number of pipes can be laid next and on top of each other
• Connections are impermeable to water and any other fluids
• They are resistant to corrosion in alkaline, acid or any other aggressive environment
• They are fine electrical insulators and also resistant to stray currents
• They’re resistant to impact
• They are resistant to ageing (with the life time of more than 50 years)

Types:

Conduit systems are classified by the wall thickness, mechanical stiffness, and material used to make the tubing. Materials may be chosen for mechanical protection, corrosion resistance, and overall cost of the installation (labor plus material cost). Wiring regulations for electrical equipment in hazardous areas may require particular types of conduit to be used to provide an approved installation.

Flexible conduits are used to connect to motors or other devices where isolation from vibration is useful, or where an excess number of fittings would be needed to use rigid connections. Electrical codes may

Application:

Automotive wiring, machinery, machine tool automation instrument, electrical motors, protect the cable wires, automotive wiring harness, machinery, ships and rail transit can also be used for machine tools such as mechanical, automation instrument, electrical motor, wear is not affected by external forces and insulation protection cable wire. Wire casing, adornment casing, is suitable for liquid and oil transportation, power line protection, the protection of the automotive wiring harness, machinery, machine tool automation instrument, etc

Production equipment and features:

Extruder for isometric range commonly deep, the gradient type screw (see soft poly catch ethylene works extruder).Corrugated forming device is mainly composed of forming dies, transmission system and control system.The forming die is made up of dozens of split up and down continuously blowing mold, lower die to caterpillar respectively fixed on the two belts.When drive system driven in mold, mold repeated closed - open the action up and down. Constitute a circular pipe forming die closed cavity, after blowing molding corrugated pipe, open mold, can make the product mold release. Corrugated forming device products forming and the traction effect at the same time.PVC plastic corrugated wire tube adopts ZBG. 33008-89 standard.
