Far from just binding the wires and elements of a cable harness together, picking out the appropriate encapsulation for the assembly can provide defense against abrasion, vibration and impact damage, extreme temperatures, moisture ingress, chemical vapours as well as fire retardancy. |
The below guide outlines a few of the advantages and specifications from the very popular options, to assist you choose the best for the assembly.
Ideal for low-risk applications, Over-Taping provides several benefits when compared with loose wires or cables. In addition to insulating the wire and creating a harness or loom significantly simpler to handle and install, Over-Taping offers economical protection against low level abrasion, vibration and impact damage.
Cables assemblies could be over-taped in a multitude of electrical tapes, specific for your needs or application. One particularly useful application for more than-Taping is the usage of coloured tape to indicate the voltage level and phase from the wire, referred to as "phasing tape". When wires are phased, a ring of tape is positioned on each end close to the termination so the reason for the wire is obvious. These table describes this usage.
Heat Shrink is certainly a versatile answer to cable protection. Heat Shrink can be used as electrical insulation, mechanical protection, cable and harness bundling, sleeving and cable identification while simultaneously providing defense against abrasion, vibration, impact and moisture ingress.
Obtainable in a multitude of thicknesses, colours and materials, Heat Shrink does apply to satisfy the person demands from the environment and application. Flame-resistant adhesive lined Heat Shrink tubing for instance provides an unbeatable degree of cable and wire protection in even hottest and many extreme of environments, including hot engines. Other these include low toxicity index for fire safety applications, high-grip material, chemical or diesel resistant and fire retardant Heat Shrink.
Perfect for jacketing and protecting an extensive selection of cable and wire assemblies, Braiding offers tough yet lightweight protection in environments where it is really not practical to get a Conduit. Braiding is particularly useful where space is restricted or even the assembly must retain flexibility, for instance when managing a cable underneath the carpet of the vehicle.
Braiding may be used at a number of levels to provide protection which range from low level abrasion, vibration and impact damage, to flame retardant Braiding ideal for high temperature environments.
Electrical Conduit provides tough yet flexible insulation and protection towards the enclosed conductors. Obtainable in metal or plastic, based on the degree of protection required, Conduit is perfect for protecting wires in exposed locations.
As well as the standard degree of protection offered against abrasion, vibration, impact and moisture ingress, Conduit may also be used in many specialised environments. When installed with adequate sealing fittings, a Conduit can offer defense against fire or explosion hazards by not permitting the flow of flammable gases and vapors to reside cables. Metal Conduit may also be used to both shield sensitive circuits from electromagnetic interference, as well as to prevent emission of these interference from enclosed power cables.
Both metal and plastic Conduit may also be bent to permit a neat installing of the assembly, this really is particularly advantageous when fitting an assembly into an irregular or curved profile.
Over-moulding is among the most complete methods for protecting an assembly and is also especially helpful for protecting fragile components and connector joints, in addition to assisting to make an assembly tamper-proof. Over Moulding fully encapsulates the contact and wire termination point, providing a mechanical bond involving the cable and circular connector and considerable environment sealing from the terminations. This added strain and flex relief significantly raises the performance and security of the connector as well as the assembly.
Over Moulding can also be probably the most great looking types of cable protection and may be used to improve the look of an item, while simultaneously protecting the wiring from abrasion, vibration, moisture ingress, impact as well as heat damage.
In environments where additional protection is required from moisture ingress, thorough water-proofing of the assembly may be accomplished by using IP rated parts. Apart from preventing moisture ingress, Waterproofed assemblies offer defense against abrasion, impact as well as heat damage and are perfect for application where units are subjected to extreme weather or high humidity either inside and out.
Waterproofed assemblies are invaluable in market sectors which are often put through challenging environmental forces, like Marine, Water Utilities, Medical, Military and Traffic Management Control Equipment.
