For a complete electronic design, the first problem is to provide power supply modules for the entire system. The stability and reliability of the power modules is the premise and basis for the smooth operation of the system. Although the 51 single-chip microcomputer has the earliest use time and the widest application range, in the actual use process, one typical problem is that compared with other series of single-chip microcomputers, the 51 single-chip microcomputer is more susceptible to interference and the program runs away, overcoming this phenomenon. An important means of emergence is to configure a stable and reliable power supply module for the microcontroller system.

Heat Resistant Sleeve For Cable

Description of Heat Resistant Sleeve For Cable Management Protection

High flame retardant braided sleeving is braided by UL 94 VO grade raw material PET mono filaments. It has excellent expandability, abrasive resistance and high flame retardant. Its flame rating can be up to VW-1.
Application electronics, automobile, high-speed rail,aviation, marine and switch cabinet wire harnessing applications where cost efficiency and durability are critical. The unique braided construction and wide expandability allows quick and easy installation over large connectors and long runs.
Ease of installation and nearly complete coverage makes fray resistance braided sleeve an ideal solution for many industrial and engineering applications.


The Cable Wire Sleeve has smooth surface, bright color and various patterns. It is an ideal product for line management and bundle application of electronics, automobiles, airplanes, ships, industry and home. For example, DVI wire mesh sets, HDMI wire net sets, motor vehicle engine line dressing, home theater wire management, computer chassis wire layout, office line management, car wiring harness, water tube protection.

PET expandable braided sleeve for cable harness is braided by environment-friendly polyester monofil. (PET,PA66), the sleeve possesses good flexibility, fire resistance, abrasive resistance and thermal insulation performance. The sleeving owns smooth surface, bright color, various patterns.
