Epta has become one of the reliable brands in the industry by producing hermetic compressor cables in 10-20 AWG sizes that comply with UL 5170 standards. These lead wire offer
excellent performance in demanding working conditions, such as household appliances, refrigerators, and cooling industries (industrial compressors, compressor motors), thanks to
their high heat and pressure resistance. Throughout the production process, every stage is meticulously cable managed using an experienced team and state-of-the-art machines.
Processes such as cable cutting, crimping, knitting, and grouping are performed in accordance with high-quality standards.

Parts that Make Up the Hermetic Lead Cable for Compressor Motors

Hermetic lead wire for compressor motors are components that ensure the organized and efficient functioning of electrical systems. These structures consist of terminals, connectors,
electrical wires, cable ties, and protective sleeves.

• Terminals

Terminals are metal connection pieces used to attach cables. While transmitting electrical signals, cables alone may struggle to deliver the signals safely, so terminals are used.
Terminals, typically made of copper, offer high electrical conductivity, and are protected with coatings such as gold, silver, or tin to increase corrosion resistance. These coatings ensure
long-lasting connections and secure electrical transmission.

• Connectors

Connectors are components that carry electrical signals and power, and are attached to the lead wire ends. They connect to electronic devices, enabling them to function. Connectors are
components at the ends of cables used in cables for household appliances, refrigerators, cooling systems (compressors, compressor motors), and air conditioning. Electrical wires are
typically made of copper. Copper offers high conductivity due to its low electrical resistance, which enhances energy efficiency.

• Polyester Braided Cable

These elements hold the cable bundles in an orderly and secure manner. They prevent the cables from damaging each other and avoid tangling. Made from durable materials such as nylon or polypropylene, these ties provide long-lasting performance even under harsh conditions. Additionally, knitting over copper cables with cable ties enhances durability and provides extra protection against external factors.

• Protective Sleeve / Sheath

Lead wires used in household appliances, refrigerators, and cooling (industrial compressors, compressor motors) sectors are equipped with sheaths that protect the bundles from external elements. These sheaths are typically made from synthetic resins like polyvinyl chloride (PVC), offering high resistance to heat, abrasion, and electrical conductivity.

Polyester Braided Cable Bundles

Polyester braided cable bundles are frequently chosen for applications where durability and security are critical. The polyester material used in the knitting adds an extra layer of
protection to the outer surface of the cable. This layer makes the cable resistant to abrasions, cuts, and other mechanical damages. Additionally, the braided structure facilitates bending,
providing flexibility and enabling the creation of more compact assemblies.

Our polyester braided cable bundles are produced in compliance with UL 5170 standards, offering the highest level of both mechanical durability and safety. The braid not only protects against mechanical damage but also provides protection against electromagnetic interference (EMI). This feature helps prevent signal distortion, ensuring the safe and uninterrupted operation of sensitive devices. Polyester braided cable bundles offer long-lasting use and protection from external elements, thereby demonstrating resistance to mechanical damage over time.

Cable Bundle Manufacturing Stages

The production of cable bundles involves a series of meticulously performed processes. These processes are carefully managed to ensure that the cable operates safely, durably, and efficiently. The first stage of production, cable cutting, ensures the preparation of cables of specific lengths.

Cable cutting is critical for the accurate progression of the production process. Incorrect cutting may negatively impact the functionality of the cable bundle. This operation is typically performed by automated machines and requires high precision.

Crimping ensures that cable onnections are secure and solid. The crimping process involves tightly placing metal terminals onto the ends of the cables. This ensures that the connection
between the cable and terminal is safe and long-lasting, while also guaranteeing the cable’s resistance to vibrations and preventing loosening over time. Additionally, it maintains optimal electrical conductivity for efficient operation.

Knitting ensures that the lead wire becomes resistant to abrasion, impacts, and mechanical damage. It also reduces electromagnetic interference (EMI), preventing signal distortion. This
process, preferred in high-security applications, enhances the flexibility of the lead wire, making assembly easier.

Grouping ensures that multiple cables are gathered together, forming an organized and compact structure. This process prevents cables from damaging each other and avoids tangling. It also facilitates the assembly and connection processes, making the cable bundle more resistant to external factors.
