Difference between ES-RYJYJ and ES-RYJ

Release time: 2024-11-12

There are significant differences between ES-RYJYJ and ES-RYJ in the application field, structural characteristics and performance parameters of the cable. The following is a detailed comparison of the two:

Application Areas

ES-RYJYJ (click to view the specific parameters of Hechang Electric Power ES-RYJYJ Cable):

Designed for energy storage application scenarios, such as mobile energy storage power station, energy storage demonstration power station, wind power energy storage system, peak energy storage system, etc.
Mainly used for battery connection, battery and inverter connection.

ES-RYJ:

RYJ series cables are commonly used in home improvement and fire-fighting wiring because of their flame-retardant and low-smoke halogen-free properties.
Suitable for rated voltage450/750V and below, heat-resistant 105 ℃ or 125 ℃ fixed wiring and power, electronic equipment internal wiring.

Structural characteristics

ES-RYJYJ:

Consists of conductor, insulation and sheath.
The conductor part is adopted6 types of conductor stranded, single copper wire more thin, high softness.
The insulation and sheathing layers are made of high-performance cross-linked polyolefin and are"Irradiation crosslinking" treatment.

ES-RYJ:

It usually has conductors and insulation, and may also include a sheath (depending on the model).
The conductors may be annealed bare copper or tinned copper soft conductors.
The insulating material may be a polyolefin.

Performance parameters

ES-RYJYJ:

Suitable for DC systems with a rated voltageDC1500V and below.
The highest temperature resistance rating isAt 125 ℃, after "irradiation crosslinking" treatment, the high temperature resistance can be increased to 125 ℃ ~ 150 ℃, and the low temperature resistance can reach -40 ℃.
It has high flexibility, acid and alkali resistance, high and low temperature resistance, large current conduction ability and high insulation.

ES-RYJ:

Conductor long-term working temperature is105 ℃ or 125 ℃.
The AC rated voltage level is450/750V。
It has excellent performance of high flame retardant, high temperature resistance, low smoke and low toxicity.

ES-RYJYJandES-RYJThe difference in performance is mainly reflected in the following aspects:

Temperature resistance

ES-RYJYJ:

The highest temperature resistance rating is125 ℃, but after "irradiation crosslinking" treatment, its high temperature resistance can be improved to 125°C ~ 150°C, and the low temperature resistance can also reach -40°C.
This excellent temperature resistance makesES-RYJYJ cables can maintain stable electrical and mechanical properties in both high and low temperature environments.

ES-RYJ:

Conductor long-term working temperature is105°C or 125°C, depending on the type and specification of the cable.
Although it also has a certain high temperature resistance, but in contrast, its scope of application may be slightly narrower.ES-RYJYJ 。

Softness and construction convenience

ES-RYJYJ:

The cable has high flexibility, is easy to bend and fold, and is easy to construct in a complex wiring environment.
This flexibility also improves the reliability and durability of the cable during long-term use.

ES-RYJ:

Although it also has a certain degree of flexibility, it may vary depending on the application scenario and cable structure.
In some cases,The softness of the ES-RYJ may not be as pronounced as ES-RYJYJ.

Insulation performance and safety

ES-RYJYJ:

The use of high-performance cross-linked polyolefin as insulation and sheath material, afterAfter "irradiation crosslinking" treatment, the insulation performance is significantly improved.
With high insulation, it can effectively prevent the occurrence of current leakage and short circuit phenomenon.
At the same time, the cable also has good flame retardant performance, meets the relevant flame retardant requirements, and improves the safety of the system.

ES-RYJ:

Polyolefin and other environmentally friendly materials are usually used as insulating layers, which have certain insulating properties and flame retardant properties.
However, in contrast, its insulation and flame retardant properties may be slightly inferior"Irradiation crosslinked" treated ES-RYJYJ cable.

Other performance

ES-RYJYJ:

It has the characteristics of acid and alkali resistance and high current conduction ability, and is suitable for various harsh environments and complex application scenarios.
The cable has compact structure and light weight, which is easy to carry and install.

ES-RYJ:

In addition to the above properties,ES-RYJ cables may also have environmental protection characteristics such as low smoke and halogen-free, and are suitable for scenarios such as interior decoration and fire wiring.
However, the specific performance may vary depending on the type and specification of the cable.

There are significant differences between ES-RYJYJ and ES-RYJ in terms of temperature resistance, flexibility and ease of construction, insulation and safety, and other properties. The choice of cable depends on the specific application and needs.
