Product Advantages
l Strong bearing capacity
The manufacturing materials mainly use high-strength and high-modulus thermosetting SMC composite materials. The axial load can reach 100KN, and the lateral load can reach 40KN.
l Strong corrosion resistance
SMC has good chemical corrosion resistance (acid,alkali, salt, organic solvent, etc.), long-term use in the underground environment will not cause changes in the internal structure and performance of the material.
l Good wave permeability
SMC material has strong electromagnetic wave penetration, which is conducive to the signal transmission of various equipment and can receive
large Part of the satellite signal, high reliability.
l Good resistance to high and low temperature
The heat distortion temperature of SMC material is extremely high, and it can maintain good performance at low temperature. The product can be used for a long time in the range of -40~100℃.
l Easy installation
The installation process is simple, the zero-based construction staff can start the installation after briefly reading the manual. Product installation is not affected by any climate and environment, construction at any time.
l Convenient transportation and cost reduction
The enclosure has a simple structure and is assembled from scattered parts. which is suitable for long-distance transportation and reduces costs.
l Long service life
SMC composite material has excellent comprehensive properties such as high and low temperature resistance,chemical corrosion resistance, providing basic guarantee for buried service life of more than 30 years.
l Low life cycle cost
During the life of the duct access box, the inside of the enclosure is cleaned, the maintenance is small, and the cost is low.
l Height adjustable
The telecom handhole has an adjustment function. The adjusting baffle and the adjusting accessories bolt work together to adjust the height of the manhole cover according to the actual construction site ground conditions, the maximum adjustment height of the manhole cover is 50mm.
