The silicon core tube products won the first place in the “Top Ten Brands of China's Silicon Core Tubes” for two consecutive years.

high performance micro tube bundle tube

product description   

The high density polyethylene (HDPE) micro tube bundle tube is composed of a high density polyethylene (HDPE) outer tube without a silicon core layer and a high density polyethylene (HDPE) micro silicon core tube (micro tube for short) containing a silicon core layer. (referred to as the cluster tube), the number of internal microtube holes can be 1 hole or porous according to the needs of use. Microtubules are used to put on micro-cables, and the outer tubes are used to enhance the overall compression resistance of the bundle tubes, and to strengthen the protection of internal micro-tubes and micro-cables.

In order to improve the anti-radiation effect and cushioning performance, Liangcheng technology technicians also developed and developed an "aluminum-plastic composite bundling tube", which was authorized by the State Intellectual Property Office, patent number: 201721048484.2.


1. Excellent physical and mechanical properties to provide adequate protection for optical cables;

2, taking into account the current cable situation and future expansion needs; single hole can be blown through the 96-core high-performance pipeline cable.

3. The optical cable lines of different customers are truly physically separated and managed separately.

Technical indicators

The technical parameters such as the size, appearance quality, ring stiffness and flat test of the microtubule inside the cluster tube are in line with the national transportation industry standard JT/T496-2018 "High-density polyethylene silicon core plastic pipe for highway underground communication pipeline", YD/T 1460- 2006 "Procedures for Air-blown Micro Cables and Fiber Units for Communication".

The products are tested by the Traffic Engineering Supervision and Inspection Center of the Ministry of Communications, and there are test reports for complete inspection projects.

The cluster tube fitting system is fully equipped, including the bundle tube mother tube connection joint, the micro tube connection interface (plug-in type), the micro tube seal plug (plug-in type), and special construction tools (including the bundle tube mother tube cutting knife, micro Tube cutting knife, bundle tube longitudinal stripping tool, etc.).

The service life of the microtubule tube is ≥50 years
