Optical fiber cable signal error-free transmission distance increased to 5890 kilometers

Recently, researchers from University College London demonstrated a new method of processing optical fiber cable signals. Researchers claim that this method can double the error-free transmission distance of signals through submarine fiber optic cables. Because the new method does not need to strengthen the signal, it has the potential to cut the cost of long-distance … Read more

What are the common types of aluminum alloy cables

Aluminum alloy cable (abbreviation: alloy cable) is different from the traditional copper core cable. This aluminum alloy cable uses high elongation aluminum alloy material. The pure aluminum is added with iron and other materials, and undergoes a compact stranding process and special Annealing treatment can “squeeze” the voids in the alloy aluminum to reduce the … Read more

Precautions for testing cross-linked cables

In recent years, silane cross-linked polyethylene cable material (hereinafter referred to as XLPE) has become the leading material for low-voltage cross-linked cable insulation because of its simple manufacturing equipment, mature technology, convenient operation, and low overall cost. At present, the commonly used XLPE is the two-step XLPE. When the cable factory produces the insulated core, … Read more

Treatment method of polyethylene insulated power cable damp and water

In urban power grid renovation projects, cables, especially polyethylene insulated power cables, have been widely used. However, due to the particularity of the cable, there are special requirements for the installation, operation and maintenance of the cable. Moisture or water in the cable reduces the insulation resistance of the cable, which is a few important … Read more

The structure and specification of YJV cable

Let me introduce to you what YJV means, yj means cross-linked polyethylene, v means polyvinyl chloride, then YJV is cross-linked polyethylene insulated PVC sheathed cable, and the range of use is for the rated voltage (U0/U) 0.6/1—26/35kv power line transmission and distribution, the rated temperature of the cable conductor is 90 degrees when in use, … Read more

How to protect cables from damage in cold winter

In winter, when laying and installing Aerial Bundle Cable (ABC) XLPE Insulated, many construction personnel will find that the wire and cable products with good quality usually have some problems, such as wire body hardening, insulation sheath falling off and damage. Many construction personnel think that the quality problems of wire and cable products have … Read more

Analysis of XLPE ACWU90 AC90 Cable Waterproof Structure

Cable waterproof structure type: For XLPE ACWU90 AC90 Cable, there are usually the following waterproof structures: 1. For single-core cables, wrap a semiconducting resistance hose on the insulation shield of the cable, wrap a common water blocking tape outside the metal shield, and then squeeze the outer sheath. The outer sheath material can be ordinary … Read more
