Cable harnesses - what are they?

Cable harnesses are an indispensable element of every electrically powered device. This applies not only to machines whose engines or specific components are powered by electricity, but also to machines that require electronic control systems or modules for control. Our company specializes in the production of cable harnesses for various purposes, because each device requires a slightly different type of cabling.

The harness itself consists of (usually) copper wire that is wrapped in a braid. In addition, the cable has external and internal insulation. The entire cable may consist of many wires. Our offer includes various cable models that differ in specific parameters, such as:

  • number of wires in the cable,
  • maximum current,
  • maximum voltage,
  • resistance,
  • type of screen (braid),
  • cable cross section,
  • durability (number of mating cycles and resistance to the operating environment).

All cable models are designed about where they will be used. Modern devices often have specific requirements, so the cabling must be precisely matched. This is also of great importance for economic reasons – it is important to use a cable that is suitable for a given purpose and does not have unnecessary (though not burdensome) parameters.

Plugs and connectors in cable harnesses

When talking about cable harnesses, it should be noted that the most critical place is considered to be the place where it is connected to the entire device. To make such a connection possible, plugs and electrical sockets are used. A wide selection of their types allows them to be adapted to a given beam. Sometimes, tin soldering is used to make the connection. Screw terminals are also available. However, these are rather outdated solutions that are not used in modern cable harnesses. The newest ones are made so that they can be installed without the need to use specialized tools. Just place the harness in the right place and then plug it in.

When analyzing the role that the plug plays in the entire electrical harness, it should be noted that it is not the plug itself that is so important. It is just a plastic element in which the most important thing is tightness and the ability to hold the connectors. If we take a closer look at this issue, it turns out that the most important thing is the quality of crimping the connector on the harness.

Manufacturers of both connectors and connectors provide specialized tools that can be used to properly crimp the connector. Generally speaking, a specific tool can be assigned to each connector type. Its use guarantees the solidity of the connection and, consequently, its durability. This translates into appropriate pressure force and thus reduces the risk of corrosion of individual elements.

The reliability of the weakest elements significantly affects the reliability of the system. Therefore, the reliability of the entire cable harness depends on whether the connector is properly crimped on the cable. As an experienced manufacturer of cable harnesses, we know this very well. That’s why we only use tools designed for specific connectors. Thanks to this, we managed to achieve the highest level of reliability.

We have extensive experience in providing cable harnesses for various industries. Our offer can be used by companies operating in the electronics market, refrigeration or railway industries. Our strength is qualified staff who know their job perfectly. We make sure that our customers receive the highest quality packages that work well.

Profitect – cable harnesses in various types

We produce cable harnesses for various purposes. These are versions such as:

  • SP type harness,
  • SP 12DC type harness,
  • WL type harness,
  • WSE type beam,
  • WMNL type harness,
  • WWPE type harness,
  • WW type package.

These include both signal cables and power cables. The former is used to transmit logical signals, i.e. to transmit data. They are used to connect individual components of larger devices, such as a computer, workstation or industrial machine. These types of cables are used in any device that uses electronic components such as control modules.
These types of harnesses are characterized by relatively low voltage and are not used to transmit power. This can only be done at very low power, but power cables are dedicated to this purpose.

Power harnesses have a different design. The cross-section of each wire is larger, and they also have different insulation and shielding. As a company specializing in the production of many types of cable harnesses, we precisely develop each variant of cable harnesses so that it is optimized for a specific application and ensures not only effective operation, but also safety.

Shielding and insulation of cable harnesses

Shielding is used to maintain EMC electromagnetic compatibility. The decision to use it is made based on the purpose of a given cable.

External electromagnetic interference may occur on signal cables carrying electrical signals with low voltage amplitude. The same thing happens for those responsible for conducting signals with small voltage changes. The standard in such cases is to use shielded cables. Moreover, it sometimes happens that paired cables are used. It is also possible to use an additional screen made of aluminum foil.

When it comes to power cables, shielding is rarely used. Applies only to cables whose task is to power the electric motor from the inverter. This is because the cable may generate electromagnetic interference, which will negatively affect the signals running through neighboring cables.

  • method of marking the core;
  • flexibility;
  • bending resistance.

Temperature characteristics are also important. Please note that in some devices the wiring harness may be in constant motion. It is then necessary to use cables with high bending strength. When choosing the right cable, pay attention to its bending radius. It may happen that constant use will damage it.

It is important to take into account the conditions in which the cable will be used. Factors that should always be taken into account include exposure to sunlight and chemical agents.

It turns out that choosing the right cable is not an easy matter. To make the right decisions, you must first determine the conditions in which the cable will be used. Thanks to this, you will find the right type that will not fail. Remember to never reach for random wires. If they are damaged, they will not enter safe mode. And this may involve a number of consequences. The most important is the inability to continue using the device.

Use of cable harnesses

The cable harnesses we produce are dedicated to many industries. Our clients include entities from the automotive, electronics and household appliances industries. Among many types of harnesses, we produce ones for fans, motors, as well as for LED lighting and lighting requiring higher voltage. We produce each type of the harness in any cable length, and we also individually adjust the cable cross-sections to the requirements of a specific installation. In addition, we use all commonly used types of connections, as well as their number and location on the harness. Nowadays, it is difficult to imagine various industries without cable harnesses. They enable efficient powering of electrical devices and the transmission of various types of data. It is also thanks to them that we can successfully operate medical equipment that often saves our lives. Cable harnesses are used in the electronics, automotive, telecommunications and automation industries. Their application is therefore extremely wide.

As these are essential components of individual devices, pay attention to this by using only

applies to the electrically conductive element as well as the screen and insulation.
