Prefabricated branch power cable

Prefabricated branch cables can be widely used in various high-rise buildings such as residential buildings, office buildings, commercial buildings, teaching buildings, research buildings, etc., as the main and trunk cables for power supply and distribution.

It can be used as a lighting and power supply network in underground mines, and as a main cable for airport runway lighting, port terminal lighting, power supply and lighting in building facilities in airports and ports; Used as lighting power supply in tunnels; It can be used as a lighting and power supply network underground in mines.

In the renovation and construction of urban power grids, buried or overhead power cables can be used as the main and trunk lines.

Used as main and main power cables in modern standard factories.

It can be used as main and main power cables in various buildings, suitable buildings, halls, pavilions, even sports facilities, swimming pools, etc.

Manufacturing Standard

The main and branch cables shall comply with GB5023.1-1997: GB5023.2-1997: GB502.3-1997 GB5023.4-1997 GB5023.7-1997 "Polyvinyl chloride insulated cables with rated voltage of 450/750V and below" and C227-2; C227-2: Relevant technical specifications and requirements of IEC227-3: EC227-4: EC227-7

Withstand AC3500V for 5 minutes without breakdown; Insulation resistance>200MQ. Withstand the weight of twice the weight of the prefabricated branch cable for 24 hours without falling off.

The joint connectors should meet the technical standard requirements, and the branch joints formed by crimping should have sufficient crimping force and contact area to ensure that the contact resistance is about the equivalent length of the conductor. During the crimping process, it is not allowed to damage the conductor materials of the main and branch cables.

The insulation material used for injection molding should be of the same type as the inner insulation or outer sheath of the main and sub cables; During the injection molding process, no damage shall be caused to the original inner insulation and outer sheath of the main and sub cables; Ensure the airtightness and water tightness of the injection molding material and the outer sheath of the main and sub cables after effective adhesion; After injection molding of the branch joint, it is pressure resistant AC 3500V, no breakdown occurs for 5 minutes; Insulation resistance>200MQ.

Advantages of prefabricated branch power cables

Significant reduction in on-site construction costs

The on-site construction period has been significantly shortened

Has higher seismic and fire resistance, fire resistance performance

More intuitive maintenance operability

Power supply safety and reliability products can be effectively activated up to 100%

Widely applicable, with multiple varieties and specifications

Unrestricted by the spatial and environmental conditions of the construction site

On site construction personnel and equipment are reduced, and the technical requirements for construction personnel are lowered

The insulation performance of the branch connector is consistent with that of the cable body, with superior insulation performance and high reliability

Users can easily choose cables of various specifications, models, cross-sectional lengths, and use them as the main and branch cables for any combination
