Products Description

Plastic insulated prefabricated branch cable is a new generation of wire and cable products, which has the characteristics of safe and reliable power supply, convenient installation and maintenance free, low overall cost, and relatively beautiful appearance. It mainly uses YJV plastic insulated power cables as the main and branch cables, with a single core and single branch structure as the main form. There are also options such as single core and multi branch, multi-core and multi branch. According to user needs, it can produce prefabricated branch cable products with special properties such as flame retardancy, fire resistance, low smoke and low halogen, and low smoke and zero halogen.
The manufacturing of prefabricated branch cables follows standards such as GB/T12706.1-2008 "Power cables with extruded insulation and accessories for rated voltages from 1kV (Um=1.2kV) to 35kV (Um=40.5kV) - Part 1: Cables with rated voltages from 1kV (Um=1.2kV) to 3kV (Um=3.6kV)". Has excellent electrical performance, such as insulation resistance ≥ 200 М Ω/KM, AC power frequency withstand voltage ≥ 3.5kV/1min, etc. At the same time, it also has good airtightness and waterproofing, and the contact resistance of the branch is small. Flame retardant and fire-resistant prefabricated branch cables have specific self extinguishing and fire resistance times.

Applicable scope

Copper core plastic insulated prefabricated branch cables with a rated voltage of 0.6/1kV can be widely used in distribution systems such as residential buildings, office buildings, hotels, hospitals, shopping malls, factories, etc.

Precautions for use

The ambient temperature during cable laying should not be lower than 0 ℃.
The maximum working temperature of copper core polyvinyl chloride insulated prefabricated branch cables is 70 ℃, while the maximum working temperature of copper core cross-linked polyethylene insulated prefabricated branch cables is 90 ℃.

The main advantages of prefabricated branch cables

1. The cost of insulation treatment for branch joints has been significantly reduced
2. Significant reduction in on-site construction costs
3. The on-site construction cycle and time have been significantly reduced
4. Reduction of on-site construction personnel and equipment; The technical requirements of construction personnel have decreased
5. Not limited by the space and environmental conditions of the construction site
6. The insulation performance of the branch link is consistent with that of the cable body, with superior insulation performance and high reliability
7. Has higher seismic, waterproof, and fire resistance performance
8. Safe and reliable power supply, with a one-time effective opening rate of up to 100%
9. Widely applicable and diverse in variety and specifications
10. Users can conveniently choose cables with specifications, models, cross-sections, and lengths as the main and branch cables for any combination
11. More intuitive maintenance operability
