Kabel izolyasiyası hər hansı bir kabelin vacib hissəsidir. O, teli örtən qeyri-keçirici materialdan hazırlanmışdır. Elektrik izolyasiyası kimi də tanınır.
İzolyasiyanın məqsədi cərəyanı kabelin qalan hissəsindən ayırmaqdır, onu məftil içərisində saxlamaq və ətraf mühitə daxil olmasının qarşısını almaq.
Eyni vaxtda, izolyasiya teli quraşdırma mühitindəki sərt şərtlərdən qoruyur və onun düzgün işləməsini təmin edir.
İzolyasiya müxtəlif materiallardan hazırlana bilər, telin hədəf tətbiqindən asılı olaraq.
Amma ümumilikdə, plastik, rezin, və floropolimerlər məftil izolyasiyasının ən çox yayılmış növləridir.
Polyvinyl chloride is resistant to moisture, yanğın, and abrasion and can be used in many environments. Misal üçün, acids, solvents, and ozone.
PVC insulated cables also have no taste or odor, so they are not toxic. The allowable temperature range for this material is -55°C to 105°C.
SR-PVC has similar resistance characteristics to PVC izolyasiya, but this material is better when maximum abrasion resistance is a priority.
Plenum PVC is also made of PVC, but is best suited for installation in interior areas with air circulation, such as raised floors or dropped ceilings.
Polyethylene is a rigid material used when high transmission speeds and low capacitance are required.
Polyethylene is also the preferred choice for coaxial cable insulation. This material is resistant to soldering, cracking, and solvents, and operates at temperatures between -65°C and 80°C.
XLPE (çarpaz bağlı polietilen) insulation is a common subtype of polyethylene insulation.
PP has similar properties to PE but is mainly used in indoor environments. The allowable temperature range for this insulation is 30°C to 80°C.
PUR is a flexible material mainly used for cables in low-temperature and marine environments. It is resistant to moisture, chemicals, and abrasion and has an operating temperature range of -60°C to 90°C.
TPR is resistant to high temperatures and harsh weather conditions and is the best choice when high processing speeds are required.
Neoprene is resistant to abrasion, oil, and solvents. This insulating material makes wires durable.
EPR is widely used in high-voltage cables – it is flexible and resistant to most irritants. the allowable temperature range for EPR cable insulation is -50°C to 160°C.
EPDM is resistant to harsh weather conditions, heat and abrasion, as well as being a strong dielectric and flexible. Its operating temperature range is -55°C- to 50°C.
Silicone is a widely used flexible synthetic rubber insulation material. This material is particularly useful in high-heat areas as it can withstand temperatures of up to 180°C.
Glass fiber is resistant to moisture and chemicals.
This glass insulation has a maximum operating temperature of 482°C and is often used in kilns, aluminum processing, and heat treatment.
SBR has similar properties to neoprene but is mainly used in Mil-C-55668 cable.
PFA is a robust and, buna görə də, durable insulating material that can be used in extreme temperatures (from -65°C to 250°C).
Polytetrafluoroethylene is a flexible thermoplastic material that is heat, oil, rütubət, and chemical resistant.
The allowable temperature range for this material is -70°C to 205°C.
FEP is typically used in down jackets and military cables due to its high flame resistance and excellent data transmission capabilities.
PVDF is also known as Kynar – it is resistant to most irritants, including flame. It is also flexible and not heavy, which makes it well suited for airy indoor environments.
