Wire harness manufacture  who be called as cable assembly manufacture or cable harness companies that specialized in custom wire harness and assembled cable for different field, such as electronic, telecommunication, homa-appliance machine or security.

Wire harness manufacture custom assembled cable and wire harness baisc on custom drawing, specification or samples which show the material about connector model and wire kinds, also connector number and wire AWG, last will be the wire contacting between all connectors and length, so that Wire harness manufacture can get all information and produce sample and mass product for customer.

Wire harness manufacture not just a maker but a creator, we can support design service if you didn't know the detail or how to build your assembled cable and wire harness, you just need to tell us your idea and using environment, we will choose the target material and using for you.

Which factor affect cable asssembly using? it indlucing pitch, contacting and environment and so on.

1.Pitch

A good cable assembly or wiring harness pitch and pins should match the wafer or connector between wire and PCB board. Too big, it;s easy to slip out when you are using, the current will break over; too small, it can't be connectted together and used. 

2.Contacting

When we are customizing wiring harness or customizing cable assembly, we should obey the currect and contacting request, can't miss anyone or take a wrong leading for current, it will broken your machine.For example, the contacting request 1-1, 2-2, 3-3, but you contact 1-3,2-2,3-1, then it maybe get a fire and burn all making.

3.Environment

Electrical wiring harness using should comply with environment when you are using. In a cold country or environment, the wire request to balance -30 to 70 degree in your special using; opposite, it should take 150-300 degree in high tempeture environment.

Equipotential busbar is a special electrical connection device designed to ensure equal potential between the electrical equipment and systems it connects, thereby preventing electrical faults and dangers caused by potential differences. It plays a vital role in electrical systems, not only effectively preventing electrical hazards caused by lightning strikes, static electricity, etc., but also optimizing current distribution and providing system stability and reliability.

In a humid or chemically corrosive environment, the equipotential busbar with a plastic base has better corrosion resistance and can resist the erosion of various chemical substances, thereby ensuring the long-term stable operation of the busbar in harsh environments and not being easily affected by environmental factors. This is especially important for some special environments, such as chemical plants and marine environments. In a highly corrosive environment, an equipotential busbar with a plastic base may be more suitable.The busbars terminal block with plastic bases are non-conductive and can reduce the risk of electrical accidents.

Plastic base busbars are low-cost and suitable for use in situations with limited budgets.

Terminal blocks play a vital role in the operation of HVAC (Heating, Ventilation, and Air Conditioning) systems, ensuring that electrical connections are secure, organized, and reliable. These components help manage the complex wiring necessary for the efficient functioning of HVAC equipment. 

Terminal blocks are used to connect these components to the control systems. By securing wires in the terminal blocks, technicians can ensure that power and signals are transmitted reliably throughout the HVAC system.

Terminal blocks simplify both the installation and maintenance of HVAC systems. During installation, wires from various components can be neatly organized and connected through wire terminal strip, reducing clutter and making the system easier to troubleshoot. In case of maintenance, specific connections can be isolated or adjusted without disturbing the entire wiring setup, making the process quicker and safer.

Safety is a critical concern in HVAC systems, which often operate in demanding environments. Terminal blocks provide a secure and insulated connection that helps prevent short circuits and electrical faults. This insulation is crucial in HVAC systems where wires may be exposed to temperature fluctuations, moisture, and other environmental factors.

Modern HVAC systems often include advanced control systems that regulate temperature, humidity, and air quality. Terminal blocks are used to connect sensors and controllers to these systems, ensuring that accurate data is transmitted and appropriate adjustments are made. This connectivity supports the precise operation of HVAC systems, contributing to energy efficiency and comfort.

Some components of HVAC systems, such as compressors and fans, require a substantial amount of power to operate. electrical terminal block are designed to handle these high currents, providing a robust connection that can withstand the electrical load without degrading over time. This durability is essential for the long-term reliability of HVAC systems.

Insulators play a crucial role in the railway industry, ensuring the safety, reliability, and efficiency of electrical systems. With the increasing adoption of electrical traction and signaling systems, the demand for high-quality insulators has grown significantly. In this blog post, we will explore the different types of insulators used in railways, focusing on Polymer Pin & Linepost Insulators, Polymer Railway Insulators, and Polymer Suspension Insulators.

The Role of Insulators in Railways

Insulators are essential components in railway systems as they prevent electrical currents from unwanted paths, thus protecting infrastructure and ensuring the smooth operation of electrical systems. They help in isolating live electrical components from the supporting structures, reducing the risk of electrical faults, and improving safety.

Types of Insulators Used in Railways

Composite insulators play a crucial role in electrical systems, offering durability and reliability in various applications. Understanding their lifespan is essential for ensuring optimal performance and safety in electrical infrastructure.

Composite insulators are made from materials such as fiberglass reinforced with epoxy or silicone rubber. They are designed to provide insulation and mechanical support in high-voltage transmission and distribution lines.

Composite insulators are widely used in overhead power lines, railway electrification systems, and substations. Common types include suspension insulators, pin insulators, and post insulators, typically rated from 10 kN to 300 kN for different voltage levels.

The normal service life of a composite insulator typically ranges from 20 to 30 years, depending on factors such as operating conditions, pollution levels, and maintenance practices. To extend the service life of composite insulators, the following precautions can be taken:

1. Regular cleaning: Insulators should be cleaned periodically to remove any accumulated dust, dirt, or pollutants. This helps prevent surface conductivity and maintains the insulator's electrical performance.

2. Pollution mitigation: If the operating environment is highly polluted, proper pollution mitigation measures should be implemented. This may involve installing additional pollution-resistant coatings or employing regular cleaning methods to minimize the accumulation of contaminants on the insulator surface.

3. Visual inspection: Regular visual inspections should be conducted to detect any signs of damage or degradation, such as cracks, chips, or discoloration. Any damaged insulators should be replaced promptly.

4. Mechanical stress management: Composite insulators should be properly installed and supported to minimize excessive mechanical stress due to factors like wind, vibrations, or system faults. Adequate mechanical safeguards should be employed to prevent undue stress on the insulator.
