拖链电缆型号有哪些？
What are the models of towline cable?
拖链电缆有很多种，如TRVVP、TRVSP、TRVV等。电缆的选择因工作条件、使用环境、用途等不同而不同。由于电缆型号不同，具有不同的特点和功能，适用于不同的工作环境。
here are many kinds of streamers, such as trvvp, trvsp, trvv, etc. The selection of cables varies with working conditions, service environment and purpose. Due to different types of cables, they have different characteristics and functions and are suitable for different working environments.
t是拖链电缆；R是软电缆；V是PVC(PVC)绝缘；V是PVC护套；S是双绞；P是铜丝织物屏蔽。
TRV型拖链电缆-铜芯丁晴PVC绝缘，丁晴PVC护套拖链电缆，一般有(2-14)*(4-6)mm2，(2-61)*(0.75-2.5)mm2近60个规格；
TRVP拖链电缆-铜芯丁晴PVC绝缘、丁晴PVC护套、镀锡铜丝屏蔽拖链电缆(7-61)*(0.75-1.5)mm2近50种规格。
TRVSP拖链电缆-铜芯丁晴PVC绝缘，丁晴PVC护套对绞制总屏蔽拖链电缆，一般为(4-61)*(0.5-2.5)mm2，(4-37)*(1.5-2.5)mm2。
RVVYP拖链电缆-即铜芯丁晴混合特殊绝缘，丁晴混合特殊护套耐油屏蔽总屏蔽拖链电缆，7-61)*(0.75-1.5)mm2近60种规格。
TRVVSP、TRVV、TRVVP三者的区别。
TRVSP表示铜芯导体、PVC绝缘、PVC护套、绞线、铜网总屏蔽软拖链、屏蔽层。
TRVV表示铜芯导体、PVC绝缘、PVC和PVC护套软拖链电缆。
铜芯导体，PVC绝缘，PVC和PVC护套铜网编成屏蔽软拖链电缆。
三种柔性拖链电缆，即TRVSP、TRVV、TRVP，均为铜芯导体，PVC绝缘材料，PVC护套。
TRVSP和TRVV、TRVVP三种柔性拖链的区别？
TRVP和TRVV的区别在于TRVV是非屏蔽柔性拖链电缆，TRVP是屏蔽柔性拖链电缆。
TRVSP和TRVV的区别在于TRVV是非屏蔽软电缆，TRVSP是双绞线屏蔽软电缆。
Meaning of streamer model:
T is the drag chain cable; R is a flexible cable; V is PVC insulation; V is PVC sheath; S is a twisted pair; P is a copper fabric shield.
Trv type drag chain cable - copper core PVC insulated, PVC sheathed drag chain cable, generally (2-14) * (4-6) mm2, (2-61) * (0.75-2.5) mm2, nearly 60 specifications;
Trvp drag chain cable - copper core PVC insulated, PVC sheathed, tinned copper wire shielded drag chain cable (7-61) * (0.75-1.5) mm2, nearly 50 specifications.
Trvsp drag chain cable - copper core PVC insulated, PVC sheathed, twisted pair total shielded drag chain cable, generally (4-61) * (0.5-2.5) mm2, (4-37) * (1.5-2.5) mm2.
Rvvyp drag chain cable - that is, copper core special insulation, special sheath, oil resistant shielding, total shielding drag chain cable, 7-61) * (0.75-1.5) mm2, nearly 60 specifications.
Trvvsp, trvv and trvvp.
Trvsp refers to copper conductor, PVC insulation, PVC sheath, stranded wire, copper net total shielding soft chain and shielding layer.
Trvv refers to copper conductor, PVC insulation, PVC and PVC sheathed flexible drag chain cable.
Copper conductor, PVC insulation, PVC and PVC sheathed copper mesh are braided into shielded flexible drag chain cable.
Three kinds of flexible towline cables, namely trvsp, trvv and trvp, are copper conductor, PVC insulation material and PVC sheath.
What is the difference between trvsp and trvv, trvvp?
The difference between trvp and trvv is that trvv is unshielded flexible towline cable and trvp is shielded flexible towline cable.
The difference between trvsp and trvv is that trvv is unshielded flexible cable and trvsp is twisted pair shielded flexible cable.
电缆使用环境中的电磁噪声非常复杂，电磁噪声的辐射或传导(EMI)会严重影响机电设备的正常运行。屏蔽层是为了防止电气线路的电磁噪声干扰，保护自身信号不受干扰。
TRVSP具有良好的电磁兼容性(EMC)特性，可作为信号传输反馈。
当选择拖链电缆时，避免噪声源向外辐射或敏感设备受到噪声源干扰时， TRVSP；当需要传输数据信号时， TRVSP，一般没有特殊要求。
Function of traction cable shielding layer:
The electromagnetic noise in the cable environment is very complex. The radiation or conduction (EMI) of electromagnetic noise will seriously affect the normal operation of mechanical and electrical equipment. Shielding layer is to prevent electromagnetic noise interference of electrical circuit and protect its own signal from interference.
Trvsp has good electromagnetic compatibility (EMC) characteristics and can be used as signal transmission feedback.
When selecting drag chain cable, trvsp is preferred to avoid noise source radiation or sensitive equipment interference; When data signals need to be transmitted, trvsp is preferred, generally without special requirements.
